SYSTEM FOR IMPROVING SEARCH TEXT

A computer-readable medium has computer-executable instructions for retrieving a search query provided by a user and locating an ambiguity in the search query that affects the optimization of the search query. The instructions also provide for requesting additional information from the user to clarify the text of the search query. Additional aspects of the invention allow the user to see and select past search queries. Further aspects of the invention automatically construct a boolean search query from a non-boolean query. Other aspects of the invention modify a search query based on its scope. In one embodiment of the invention a search query is modified based on natural language parse data produced by performing a natural language parse of the search query.
