1. A text index, comprising a data structure stored in a memory for access by at least one application program being executed on a data processing system, for use in the preparation of semantically associated text searches of electronic documents in a search engine, said text index comprising:

  • one or more content records corresponding to an electronic document, the content records identifying one or more text terms present within the electronic document;

    one or more term association records associating a text term present within the electronic document identified by a content record with a pre-determined semantic definition of the text term;

    one or more content association records linking a term association record of the one or more term association records with a content record of the one or more content records;

    wherein a user is enabled to provide one or more user-defined text search terms desired to be located within the text index;

    wherein, for user-defined text search terms having term association records within the search index, the user is iteratively presented a list of one or more pre-determined semantic definitions associated with each of the one or more user-defined text search terms, enabling the user to select a pre-determined semantic definition of those one or more user-defined text search terms;

    wherein the one or more content association records contained within the text index are searched using the user-defined text search terms to locate electronic documents previously catalogued as containing the one or more user-defined text search terms in association with the selected pre-determined semantic definitions, to form a semantically relevant results set;

    wherein new term association records are updated or created during the use of the text index by enabling a user to select pre-determined semantic definitions for association with user-defined text search terms; and

    wherein new content association records are updated or created during the use of the text index in a search, by associating a particular electronic document with the use-defined text search terms, and selected pre-determined semantic definitions of the user-defined text search terms, used to locate the particular electronic document.
