Disclosed are apparatus and methods for providing a word or phrase index regarding a particular set of search results. In specific embodiments, a word or phrase index for summarizing the words or phrases (or a subset of same) within the particular search results may be determined. This index may be similar to the inverted index used by some search engines so that each of a plurality of words or phrases are associated with a plurality of search results (e.g., web pages and/or their cached copies) that contain such each word or phrase. The index is determined based on the search results, and the index for the search results is then provided along with the search results. The entries of the provided search result index are preferably selectable so that a user can access the search results that contain at least one of the listed word or phrase in the index.
