Abstract
Front end preprocessing modifies queries to get them in better form for presentation to a variety of data sources. The queries are modified by grouping terms as phrases, correcting spelling errors, and augmenting the query with category terms that trigger query execution on certain data sources. Context information about a particular user as well as information about previous queries by other uses are also used to modify the query to better reflect the user's intent.
