Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	<b>Portfolio Turnover </b>
Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2018 was 69% of the average value of its portfolio.

Expense Example [Heading]	rr_ExpenseExampleHeading	<b>Expense Example </b>
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Investor, Class R and/or Class R6 Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R and/or Class R6 Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the expense limitation arrangement for only the first year). The Example does not take into account brokerage commissions that you may pay on your purchases and sales of Institutional Shares of the Fund. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	<b>Principal Strategy </b>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) (“Net Assets”) in equity investments. The Fund will generally invest in equity securities that the Investment Adviser believes have favorable prospects for capital appreciation and/or dividend-paying ability. Although the Fund will invest primarily in publicly traded U.S. securities, including preferred and convertible securities, master limited partnerships (“MLPs”) and real estate investment trusts (“REITs”), it may invest up to 25% of its Net Assets in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies. The Investment Adviser expects that the Fund’s investments will be weighted in favor of companies that pay dividends or other current distributions. The Fund’s equity investment process involves: (1) using multiple industry-specific valuation metrics to identify real economic value and company potential in stocks, screened by valuation, profitability and business characteristics; (2) conducting in-depth company research and assessing overall business quality; and (3) buying those securities that a sector portfolio manager recommends, taking into account feedback from the rest of the portfolio management team. The Investment Adviser may decide to sell a position for various reasons, including valuation and price considerations, readjustment of the Investment Adviser’s outlook based on subsequent events, the Investment Adviser’s ongoing assessment of the quality and effectiveness of management, if new investment ideas offer the potential for better risk/reward profiles than existing holdings, or for risk management purposes. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions. The Fund may also invest up to 20% of its Net Assets in fixed income securities, such as government, corporate and bank debt obligations. The Fund seeks to generate additional cash flow and may reduce volatility by the sale of call options on the S&P 500® Index or other regional stock market indices (or related exchange-traded funds (“ETFs”)). The Fund expects that, under normal circumstances, it will sell call options in an amount that is between 0% and 30% of the value of the Fund’s portfolio. As the seller of the call options, the Fund will receive cash (the “premium”) from the purchaser. If the purchaser exercises the option, the Fund pays the purchaser the difference between the price of the index and the exercise price of the option. The premium, the exercise price and the market price of the index determine the gain or loss realized by the Fund as the seller of the call option. During periods in which the U.S. equity markets are generally unchanged or falling, or in a modestly rising market where the income from premiums exceeds the aggregate appreciation of the underlying index over its exercise price, a diversified portfolio receiving premiums from its call option writing strategy may outperform the same portfolio without such an options strategy. However, in rising markets where the aggregate appreciation of the underlying index over its exercise price exceeds the income from premiums, a portfolio with a call writing strategy could significantly underperform the same portfolio without the options. The Fund’s benchmark index is the Russell 1000® Value Index.
Risk [Heading]	rr_RiskHeading	<b>Principal Risks of the Fund </b>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing. Foreign and Emerging Countries Risk.  Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. The imposition of exchange controls, sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and other governments, or from problems in share registration, settlement or custody, may also result in losses. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. These risks may be more pronounced in connection with the Fund’s investments in securities of issuers located in emerging countries. Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Value stocks are those believed to be undervalued in comparison to their peers, due to market, company-specific or other factors. Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio. Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Master Limited Partnership Risk.  Investments in securities of an MLP involve risks that differ from investments in common stock, including risks related to limited control and limited rights to vote on matters affecting the MLP. Certain MLP securities may trade in lower volumes due to their smaller capitalizations, and may be subject to more abrupt or erratic price movements and lower market liquidity. MLPs are generally considered interest-rate sensitive investments. During periods of interest rate volatility, these investments may not provide attractive returns. Investments in securities of an MLP also include tax-related risks. For example, to the extent a distribution received by the Fund from an MLP is treated as a return of capital, the Fund’s adjusted tax basis in the interests of the MLP may be reduced, which will result in an increase in an amount of income or gain (or decrease in the amount of loss) that will be recognized by the Fund for tax purposes upon the sale of any such interests or upon subsequent distributions in respect of such interests. Option Writing Risk.  Writing (selling) call options limits the opportunity to profit from an increase in the market value of stocks in exchange for up-front cash (the premium) at the time of selling the call option. In a rising market, the Fund could significantly underperform the market. Furthermore, the Fund’s call option writing strategies may not fully protect it against market declines because the Fund will continue to bear the risk of a decline in the value of its portfolio securities. In a sharply-falling equity market, the Fund will likely also experience sharp declines in its net asset value (“NAV”). REIT Risk.  Risks associated with investments such as REITs in the real estate industry include, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage financing, variations in rental income, neighborhood values or the appeal of property to tenants; interest rates; overbuilding; extended vacancies of properties; increases in competition, property taxes and operating expenses; and changes in zoning laws. REITs whose underlying properties are concentrated in a particular industry or geographic region are subject to risks affecting such industries and regions. The securities of REITs involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements because of interest rate changes, economic conditions and other factors. Securities of such issuers may lack sufficient market liquidity to enable the Fund to effect sales at an advantageous time or without a substantial drop in price. Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The Investment Adviser has agreed to reduce or limit "Other Expenses" (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund's average daily net assets. Additionally, Goldman Sachs & Co. LLC ("Goldman Sachs"), the Fund's transfer agent, has agreed to waive a portion of its transfer agency fee (a component of "Other Expenses") equal to 0.04% as an annual percentage rate of the average daily net assets attributable to Class A, Class C, Investor and Class R Shares of the Fund. These arrangements will remain in effect through at least December 28, 2019, and prior to such date the Investment Adviser and Goldman Sachs may not terminate the arrangements without the approval of the Board of Trustees.

[3] After Expense Limitation

[4] Class C Shares automatically convert into Class A Shares ten years after the purchase date. The Since Inception performance for Class C Shares does not reflect the conversion to Class A Shares after the first ten years of performance.

[5] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of Class R6 Shares shown in the table above is that of Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.
