Real-time query expansion (RTQE) is a process of supplementing an original query with addition terms or expansion choices that are ranked according to some figure of merit and presented while users are still formulating their queries. As disclosed herein, phrases may be presented and one or more terms of a focused-on phrase may be pinned (as desirable to the user). Subsequent lists may be presented as a function of pinned terms and/or user input. In one embodiment, a placeholder may be substituted for one or more pinned terms if less than some predetermined threshold of phrases is able to be presented based upon the pinned terms and/or user input, and another list of phrases may be presented as a function of a query using fewer than all the pinned terms. The placeholder may allow out-of-index phrases to be formed, for example, based upon two or more phrases and/or terms input by the user.
