1. A search system for searching for a query sentence in a document to be retrieved, comprising:
- at least one analysis component means for analyzing said query sentence;
at least one extraction component for extracting location constraint data from the results of said analysis to provide a partial-order relationship; and
at least one search component for searching said document, without performing an analysis of said document, for sentences that match said partial-order relationship.

Abstract
A search request is syntactically analyzed, and location constraint data for keywords and function words (FNWORD) are extracted that constitute partial-order relationships. A document, which is to be retrieved and for which no syntactic analysis is required, is searched for that contains a sentence that matches the partial-order relationship. In the search for the document containing the sentence that matches the partial-order relationship, a sentence having a short context that matches the partial-order relationship is regarded as a sentence that has a higher similarity.
