INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD

摘要

This invention is directed at providing a technique for implementing higher-speed search processing for a binary structured document. A search query conversion means converts a search query for a structured document by converting each node building the search query into a corresponding index by using a vocabulary list. A document analysis means specifies an index corresponding to each node building the structured document by using the vocabulary list. A search query evaluation means searches for part of the structured document that corresponds to the converted search query, by using each index described in the converted search query and the index corresponding to each node that is specified by the document analysis means.
