A method includes receiving a search query including clause text to be searched and executing the search query against the database. The method includes receiving a set of results, the set of results including documents that include a version of the clause text, and normalizing the set of search results. The method includes grouping the normalized set of search results into one or more groups of results, each group including documents containing a version of the clause text that is semantically equivalent to each other document in the group. The method includes receiving an indication of a selection of a particular group from among the one or more groups of results and causing display of at least a portion of the particular version of the clause text.
