Abstract: A technique including receiving a search query; identifying a first original query term based on the query; identifying a first expanded query term related to the first original query term; determining a first lexical distance between the first original query term and the first expanded query term; determining a first weight for the first expanded query term based on the determined first lexical distance; identifying a plurality of documents, from among a corpus of documents, as each relevant to the search query, the plurality of documents including a first document identified based on its inclusion of the first expanded query term; ranking the plurality of documents, with the ranking of the first document being based upon the calculated first weight; and generating a response to the search query identifying two or more of the plurality of documents, ordered according to the ranking.
