Abstract
The present invention relates to a document search apparatus for searching a predetermined corpus for a document file whose content is related to text for searching. The apparatus stores index information that indicates the position in a document and the position in a morpheme for a respective gram. Upon the receipt of the input of text for searching, from a user, the document search apparatus extracts a morpheme and a gram. Then, upon the indexing of the rarity of the morpheme in the corpus and the detection of a document file that contains the morpheme, the number of times such a morpheme appears in the document file is counted as an appearance frequency. From the estimate number and the appearance frequency regarding the morpheme, the relevance of the contents between the text for searching and the document file is indexed as a relevance score.
