Abstract
A search query is applied to documents in a document repository wherein the documents are organized into a hierarchy. A search engine searches the hierarchy to return documents which match a query term either directly or indirectly. A specific embodiment of the search engine organizes the query term into individual subterms and matches the subterms against documents, returning only those documents which indirectly match the entire search query term and directly match at least one of the query subterms.
