Abstract
An index storing unit stores, in a page as a fixed-length storage area, a vocabulary index which associates vocabulary identifiers for identifying vocabularies included in a structured document having a layered logical structure and specific information for specifying positions where the vocabularies appear. A characteristic analyzing unit analyzes a characteristic concerning a distribution of the specific information included in the vocabulary index stored in the page. A dividing unit divides the page into a plurality of blocks including one of a plurality of the vocabulary indexes based on the characteristic analyzed by the characteristic analyzing unit, calculates a first range representing a range of the specific information of the vocabulary indexes included in the blocks, and stores the first range in each of the divided blocks in the index storing unit.
