1. A computer-implemented method comprising:
receiving a search query; obtaining one or more search results responsive to the search query, wherein a first search result of the one or more search results identifies a resource including text; computing a respective similarity measure between the search query and each of a plurality of contiguous portions of text of the resource; selecting a suggested query phrase from a first contiguous portion of text of the resource having a highest computed similarity measure with the search query; generating a first search result snippet to be presented as part of the first search result in a presentation of the one or more search results, wherein the first search result snippet presented as part of the first search result includes the suggested query phrase as a selectable user interface element for a user to submit the suggested query phrase as a new search query; and providing the presentation of the one or more search results, including the first search result snippet as part of the first search result, in response to the search query.
