Abstract: This disclosure relates to performing a query for a search term of a database containing a plurality of structured documents. Those structured documents that do not include the search term are ferreted or filtered out during an initial search. Matched structured documents which are those structured documents that do contain the search term are evaluated by ranking the individual elements based on how well each individual element matches the search term, and indicating to the user the ranking of the individual elements wherein the individual elements can be accessed by the user.

Abstract: The described subject matter provides systems and procedures to make query similarity determinations, wherein the queries are used in information retrieval operations. A same document and/or multiple similar documents are identified that have been selected by a user in response to multiple queries. Responsive to identifying the same document and/or the similar documents, a query cluster is generated that indicates that the queries used to obtain the same and/or similar documents. This is accomplished in a manner that is independent of whether individual ones of the queries are compositionally similar with respect to other ones of the queries.
