The system includes a corpus including a plurality of electronic documents that are domain tagged at a document level and analyzed based on the tags to identify word usage patterns. An index of word usage patterns is provided that indexes the plurality of documents in the corpus according to their word usage patterns. The system also includes a query pre-processing module that receives a query from a user, and analyzes the query to determine probable word usage patterns in the query. The system further includes a processor that uses the index to identify documents having word usage patterns that matches the probable word usage patterns in the query as a candidate electronic document, and retrieves the candidate electronic document.
