<p>A search and retrieval permits a user to search free text within sections of schema independent documents. The documents, which may include structured (Fig. 1, item 120), semi-structured (Fig. 1, item 130), and unstructured documents (Fig. 1, item 140), contain text organized into a plurality of sections, such as XML tags (Fig. 3a). The repository of documents is schema independent, such that the search system does not require pre-defined fields for the sections. To execute a search, the search system receives a query that specifies at least one section and at least one free text query construct for text within the section (Fig. 5, item 1210-1290). In general, the free text query construct specifies at least one free search condition. The search system identifies sections in the repository of documents as specified in the query, and evaluates the free text query construct for the text within sections to determine whether the free text search condition is met.</p> |
