Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“ U.S. GAAP ”) and applicable rules and regulations of the Securities and Exchange Commission (“ SEC ”) regarding interim financial reporting. Certain information and note disclosures included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 , which was filed with the SEC on February 25, 2016 (“ 2015 Form 10-K ”). The condensed consolidated balance sheet as of December 31, 2015 , included herein, was derived from the audited financial statements as of that date but does not include all disclosures, including notes required by U.S. GAAP . In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial positions, results of operations and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year 2016 or any future period. Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management evaluates estimates on a regular basis including those relating to revenue recognition, allowance for doubtful accounts, goodwill, intangible assets, valuation of deferred income taxes, stock-based compensation, and unrecognized tax benefits, among others. Actual results could differ from those estimates and such differences may have a material impact on the Company’s condensed consolidated financial statements and footnotes. Significant Accounting Policies The Company’s significant accounting policies are described in Note 2 of the Notes to Consolidated Financial Statements in its 2015 Form 10-K . There have been no significant changes to these policies during the six months ended June 30, 2016 . Comprehensive Income Comprehensive income consists of net income and other comprehensive income . Other comprehensive income includes certain changes in equity that are excluded from net income, specifically unrealized gains on available-for-sale investments. Except for net realized gain on investments which was not significant, there were no reclassifications out of accumulated other comprehensive income that affected net income during the three and six months ended June 30, 2016 and 2015 . Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“ FASB ”) issued Accounting Standards Update (“ ASU ”) No. 2014-09, Revenue from Contracts with Customers (“ ASU 2014-09 ”), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This standard also requires significantly expanded disclosures about revenue recognition. In August 2015, the FASB deferred the effective date of this standard by one year. In March, April and May 2016, the FASB clarified the implementation guidance on principal versus agent, identifying performance obligations, licensing, collectability, noncash consideration, presentation of sales tax, and certain other transition matters. The new effective date for public entities will be for fiscal years, and interim periods within those years, beginning after December 15, 2017, but entities will be permitted to early adopt the standard as of the original effective date. The Company has not yet developed an expectation of the impact that adoption will have on its consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”), which updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. ASU 2016-01 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and early adoption is not permitted. The Company has not yet developed an expectation of the impact that adoption may have on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), which requires lessees to put most leases on their balance sheets but recognize the expenses on their income statements in a manner similar to current practice. ASU 2016-02 states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. The new standard is effective for interim and annual periods beginning after December 15, 2018 and early adoption is permitted. The Company has not yet developed an expectation of the impact that adoption may have on its consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718) (“ASU 2016-09”). This standard makes several modifications to Topic 718 related to the accounting for forfeitures, employer tax withholding on share-based compensation and the financial statement presentation of excess tax benefits or deficiencies. ASU 2016-09 also clarifies the statement of cash flows presentation for certain components of share-based awards. The standard is effective for interim and annual reporting periods beginning after December 15, 2016, although early adoption is permitted. The Company has not yet developed an expectation of the impact that adoption may have on its consolidated financial statements.

Earnings Per Share [Abstract]
Net Income (Loss) Per Share of Common Stock	Net income per share of common stock is calculated by dividing net income by the weighted average shares of common stock outstanding during the period. Diluted net income per share of common stock is calculated by dividing net income by the weighted average shares of common stock outstanding and potential shares of common stock during the period. Potential shares of common stock include dilutive shares attributable to the assumed exercise of stock options, restricted stock unit awards (“ RSU s”), performance-vesting RSUs, performance share awards (“ Performance Awards ”), and Employee Stock Purchase Plan (“ ESPP ”) shares using the treasury stock method, if dilutive. The components of net income per share of common stock were as follows: Three Months ended June 30, Six Months ended June 30, 2016 2015 2016 2015 (in thousands, except share and per share amounts) Net income $ 10,588 $ 7,630 $ 13,094 $ 11,214 Basic shares: Weighted average common shares outstanding 29,578,630 29,092,149 29,643,779 28,931,042 Diluted shares: Weighted average shares used to compute basic net income per share 29,578,630 29,092,149 29,643,779 28,931,042 Effect of potentially dilutive securities: Employee stock options, RSUs, performance-vesting RSUs, Performance Awards and ESPP shares 1,609,969 1,715,268 1,635,733 1,712,029 Weighted average shares used to compute diluted net income per share 31,188,599 30,807,417 31,279,512 30,643,071 Net income per share: Basic $ 0.36 $ 0.26 $ 0.44 $ 0.39 Diluted $ 0.34 $ 0.25 $ 0.42 $ 0.37 The following potential weighted average common shares were excluded from the computation of diluted net income per share, as their effect would have been anti-dilutive: Three Months ended June 30, Six Months ended June 30, 2016 2015 2016 2015 Employee stock options and awards 31,721 190,186 237,177 395,182 Performance-vesting RSUs and Performance Awards are included in the diluted shares outstanding for each period if the established performance criteria have been met at the end of the respective periods. However, if none of the required performance criteria have been met for such awards, the Company includes the number of shares that would be issuable if the end of the reporting period were the end of the contingency period. Accordingly, in addition to the employee stock options and awards noted above, 136,598 and 186,312 shares underlying performance-vesting RSUs and Performance Awards were excluded from the dilutive shares outstanding for each of the three and six months ended June 30, 2016 and 2015 , respectively.

Financial Instruments and Fair Value Measurements [Abstract]
Financial Instruments and Fair Value Measurements	Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are classified and disclosed in one of the following three categories: Level 1 — Valuations based on quoted prices in active markets for identical assets or liabilities. Level 2 — Valuations based on other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Valuations based on inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the assets or liabilities. The following tables set forth by level within the fair value hierarchy the Company’s financial assets that were accounted for at fair value on a recurring basis: Fair Value at Fair Value Measurements Using Inputs Considered as June 30, 2016 Level 1 Level 2 Cash equivalents: Money market funds $ 2,687 $ 2,687 $ — Corporate notes and obligations 191 — 191 U.S. government and government agency obligations 225 — 225 Investments: Certificates of deposit 11,593 — 11,593 Corporate notes and obligations 31,009 — 31,009 Municipal obligations 7,176 — 7,176 U.S. government and government agency obligations 38,673 5,314 33,359 $ 91,554 $ 8,001 $ 83,553 Fair Value at Fair Value Measurements Using Inputs Considered as December 31, 2015 Level 1 Level 2 Cash equivalents: Money market funds $ 6,788 $ 6,788 $ — Investments: Certificates of deposit 12,928 — 12,928 Corporate notes and obligations 28,205 — 28,205 Municipal obligations 2,648 — 2,648 U.S. government and government agency obligations 60,667 19,429 41,238 $ 111,236 $ 26,217 $ 85,019 The Company classifies its money market funds that are specifically backed by debt securities and U.S. government obligations as Level 1 instruments, due to the use of observable market prices for identical securities that are traded in active markets . Valuation of the Company’s marketable securities investments classified as Level 2 is achieved primarily through broker quotes when such investments exist in a non-active market. At June 30, 2016 and December 31, 2015 , the Company did not have any assets or liabilities that were valued using Level 3 inputs. For the three and six months ended June 30, 2016 and 2015 , there were no transfers of financial instruments between the levels. For the three and six months ended June 30, 2016 , the Company recognized interest income from financial instruments of $0.2 million and $0.4 million , respectively. For the three and six months ended June 30, 2015 , the Company recognized interest income from financial instruments of $0.2 million and $0.3 million , respectively. Gross realized gains and losses from the sale of investments were not significant during the three and six months ended June 30, 2016 and 2015 . At June 30, 2016 , $50.0 million of the Company's investments had a contractual maturity of one year or less and $41.6 million had a contractual maturity of one to three years. The carrying amounts, gross unrealized gains and losses and estimated fair value of cash and cash equivalents and both short-term and long-term investments consisted of the following: June 30, 2016 Amortized Cost Unrealized Gains Unrealized Losses Carrying or Fair Value (in thousands) Cash and cash equivalents: Cash $ 41,506 $ — $ — $ 41,506 Money market funds 2,687 — — 2,687 Corporate notes and obligations 191 — — 191 U.S. government and government agency obligations 225 — — 225 $ 44,609 $ — $ — $ 44,609 Investments: Corporate notes and obligations $ 30,951 $ 66 $ (8 ) $ 31,009 Certificates of deposit 11,563 31 (1 ) 11,593 Municipal obligations 7,159 17 — 7,176 U.S. government and government agency obligations 38,606 71 (4 ) 38,673 $ 88,279 $ 185 $ (13 ) $ 88,451 December 31, 2015 Amortized Cost Unrealized Gains Unrealized Losses Carrying or Fair Value (in thousands) Cash and cash equivalents: Cash $ 27,608 $ — $ — $ 27,608 Money market funds 6,788 — — 6,788 $ 34,396 $ — $ — $ 34,396 Investments: Corporate notes and obligations $ 28,314 $ 1 $ (110 ) $ 28,205 Certificates of deposit 12,945 5 (22 ) 12,928 Municipal obligations 2,647 1 — 2,648 U.S. government and government agency obligations 60,799 10 (142 ) 60,667 $ 104,705 $ 17 $ (274 ) $ 104,448 The following table shows the gross unrealized losses and the related fair values of the Company’s investments that have been in a continuous unrealized loss position.

Income Tax Disclosure [Abstract]
Income Taxes	The Company computes its interim provision for income taxes by applying the estimated annual effective tax rate to the year-to-date income from recurring operations and adjusts the provision for discrete tax items recorded in the period. The Company evaluates and updates its estimated annual effective income tax rate on a quarterly basis. The estimated annual effective tax rate as of June 30, 2016 and 2015 was 37.4% and 42.0% , respectively. Three Months ended June 30, Six Months ended June 30, 2016 2015 2016 2015 (dollars in thousands) Income tax provision 6,258 5,368 7,474 8,396 Effective tax rate 37.2 % 41.3 % 36.3 % 42.8 % The difference between the federal statutory rate of 35% and the Company’s estimated effective tax rate for the three and six months ended June 30, 2016 was primarily due to the Company’s state income tax provision, non-deductible stock-based compensation expenses, and R&D credits. The Company realized a tax benefit of $1.2 million for the three and six months ended June 30, 2016 related to the exercise of employee stock options and the vesting of RSUs, performance-vesting RSUs and Performance Awards. The Company realized a tax benefit of $0.9 million and $3.9 million for the three and six months ended June 30, 2015 related to the exercise of employee stock options and the vesting of RSUs, performance-vesting RSUs and Performance Awards. The net income tax benefit in excess of the expenses recorded for financial reporting purposes has been recorded as an increase to additional paid-in capital and is reflected as a financing cash inflow in the condensed consolidated statements of cash flows. The Company’s tax positions are subject to income tax audits by multiple tax jurisdictions. The Company accounts for uncertain tax positions and believes that it has provided adequate reserves for its unrecognized tax benefits for all tax years still open for assessment. The Company also believes that it does not have any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly increase or decrease within the next twelve months. The Company has a policy to classify accrued interest and penalties associated with uncertain tax positions together with the related liability in the balance sheet, and to include the expenses incurred related to such accruals in the provision for income taxes. There were no interest or penalties included in the provision for income taxes during the six months ended June 30, 2016 and 2015 , respectively. The Company is currently under examination by the U.S. Internal Revenue Service for the 2013 tax year. At this time, the Company is not able to estimate the potential impact that the examination may have on income tax expense. If the examination is resolved unfavorably, it may have a negative impact on the Company’s results of operations.

Restricted Stock Units, Performance-Vesting Restricted Stock Units, and Performance Awards The Performance Awards granted represent the right to receive shares of the Company’s common stock, contingent upon the achievement of certain of the Company’s performance metrics during the performance period. On a date subsequent to the performance period, the Compensation Committee of the Board of Directors (the “ Compensation Committee ”) determines and approves the achievement of the performance goals (the “ Determination Date ”) and the earned shares are issued, with 25% of the shares vested upon issuance and the remaining shares to vest 25% on each of the first three anniversaries of the Determination Date , subject to the continuous employment of the participant through such dates. In October 2015, in connection with the acquisition of Mortgage Returns, the Company agreed to pay up to 29,006 of performance-vesting RSUs for a total value of $2.0 million to the former Chief Executive Officer of Mortgage Returns upon achievement of certain performance criteria and a service requirement during the performance period of October 23, 2015 through October 23, 2019. The performance-vesting RSUs will vest annually based on the achievement of the performance criteria and the service requirement. In February 2016, the Company granted Mr. Anderman 6,692 performance-vesting RSUs and an option to purchase 14,506 shares of Company common stock. Mr. Anderman may earn between zero and 2.0 shares of common stock for each performance-vesting RSU. As of June 30, 2016 , the Company expects that each of these performance-vesting RSUs will convert to 1.15 shares of common stock on the Determination Date. Additionally, in February 2016, the Company granted 64,449 Performance Awards with a performance period of January 1, 2016 through December 31, 2016 to designated participants under the 2011 Plan.

Accounting Policies [Abstract]
Principles of Consolidation [Policy Text Block]	Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management evaluates estimates on a regular basis including those relating to revenue recognition, allowance for doubtful accounts, goodwill, intangible assets, valuation of deferred income taxes, stock-based compensation, and unrecognized tax benefits, among others. Actual results could differ from those estimates and such differences may have a material impact on the Company’s condensed consolidated financial statements and footnotes.
Significant Accounting Policies [Text Block]	Significant Accounting Policies The Company’s significant accounting policies are described in Note 2 of the Notes to Consolidated Financial Statements in its 2015 Form 10-K . There have been no significant changes to these policies during the six months ended June 30, 2016 .
Comprehensive Income [Policy Text Block]	Comprehensive Income Comprehensive income consists of net income and other comprehensive income . Other comprehensive income includes certain changes in equity that are excluded from net income, specifically unrealized gains on available-for-sale investments. Except for net realized gain on investments which was not significant, there were no reclassifications out of accumulated other comprehensive income that affected net income during the three and six months ended June 30, 2016 and 2015
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“ FASB ”) issued Accounting Standards Update (“ ASU ”) No. 2014-09, Revenue from Contracts with Customers (“ ASU 2014-09 ”), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This standard also requires significantly expanded disclosures about revenue recognition. In August 2015, the FASB deferred the effective date of this standard by one year. In March, April and May 2016, the FASB clarified the implementation guidance on principal versus agent, identifying performance obligations, licensing, collectability, noncash consideration, presentation of sales tax, and certain other transition matters. The new effective date for public entities will be for fiscal years, and interim periods within those years, beginning after December 15, 2017, but entities will be permitted to early adopt the standard as of the original effective date. The Company has not yet developed an expectation of the impact that adoption will have on its consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”), which updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. ASU 2016-01 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and early adoption is not permitted. The Company has not yet developed an expectation of the impact that adoption may have on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), which requires lessees to put most leases on their balance sheets but recognize the expenses on their income statements in a manner similar to current practice. ASU 2016-02 states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. The new standard is effective for interim and annual periods beginning after December 15, 2018 and early adoption is permitted. The Company has not yet developed an expectation of the impact that adoption may have on its consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718) (“ASU 2016-09”). This standard makes several modifications to Topic 718 related to the accounting for forfeitures, employer tax withholding on share-based compensation and the financial statement presentation of excess tax benefits or deficiencies. ASU 2016-09 also clarifies the statement of cash flows presentation for certain components of share-based awards. The standard is effective for interim and annual reporting periods beginning after December 15, 2016, although early adoption is permitted. The Company has not yet developed an expectation of the impact that adoption may have on its consolidated financial statements.
