1. A computer-implemented method, comprising: receiving, from a computing device operated by a user, a partial search query of the user; identifying a superset of candidate navigational search results based on the partial search query; selecting a subset of navigational search results from the superset based at least in part on one or more signals; generating data to render a search result presentation interface that transitions, after a pause without user activity, between presenting the user with a first graphical user interface that includes the subset of navigational search results independently of other search results that are responsive to the partial search query and a second graphical user interface that includes the superset of candidate navigational search results; and delivering the data to the computing device operated by the user.
