A method of performing automated collection selection relative to a plurality of document collections, each including one or more documents, using a list of qualified terms developed from an input query text. The method comprises the steps of: (a) parsing the input query text to select single-word terms and multiple-word phrase terms from the query text by exclusion of predetermined context-free single-word terms and punctuation; (b) applying each such selected term against a meta-index descriptive of the document collections; (c) determining cumulative rankings for the document collections relative to each such selected term normalized against the plurality of document collections; and (d) selecting a set of the document collections having the highest relative cumulative rankings.

[ We claim:] [1.] A method of performing automated document collection selection and document selection relative to a plurality of independently maintained document collections, each including a plurality of documents, using a list of qualified terms developed from an input query text, said method comprising the steps of:providing a meta-index having meta-index values identifying corresponding ones of the document collections and information about documents in the corresponding ones of the document collections;parsing said input query text to select single-word terms and multiple-word phrase terms from said query text by exclusion of predetermined context-free single-word terms and punctuation;applying each such selected term against the meta-index values in said meta-index to determine correlation between the selected terms and the meta-index values;determining cumulative rankings for said document collections based upon said correlation relative to each such selected term normalized against said plurality of document collections; andselecting a subset of said document collections having the highest relative cumulative rankings whereby said subset of said document collections is established to be the most appropriate subset of said plurality of document collections to search using said input query text,searching each of said subset of document collections with said input query text to select documents correlating to said query text.
