A text cataloging method includes a step of cataloging already-analyzed-text data obtained from an analysis of a logical structure of a text to be cataloged in a text database, a step of creating a structure index by sequentially superposing logical structures of texts to be cataloged, wherein a single metaelement is used for representing a group of elements in the texts having the same position of appearance in one of the texts and the same element type, a single piece of meta-character-string data is used for representing a group of pieces of character-string data in the texts having the same position of appearance in one of the texts, and a context identifier is assigned to each metanode composing a tree-like structure of the structure index for uniquely identifying the metanode; a step of generating structured-full-text data composed of definitions of associative relations between all pieces of character-string data-included in already-analyzed-text data of each text to be cataloged, and context identifiers of pieces of meta-character-string data in the structure index used for representing the pieces of character-string data; and a character-string-index updating step, including the sub-steps of extracting partial character strings, generating structured-character-position information, and updating a character-string index.

[ What is claimed is:] [9.] A text searching system, comprising:a text cataloging sub-system in which a plurality of texts are cataloged for use as text search objects in a text search operation;a text searching server that causes a text database to be searched in response to a text search request;a text searching client from which a text search request is issued to the text searching server; anda network connecting the text cataloging sub-system, the text searching server, and the text searching client;wherein the text cataloging sub-system creates a structure index based on the cataloging of the plurality of texts, the structure index containing context identifiers of character-string data derived from the cataloged texts;wherein said structure index has a tree-like structure composed of a plurality of metanodes;wherein a context identifier that uniquely identifies one of said metanodes is assigned to each metanode of said structure index;wherein a group of structure elements having the same position of appearance and the same element type for a plurality of texts are represented by a single metanode;wherein the text search request issued by the text searching client includes a search condition that is translated into a condition specification by the text searching server, from which condition specification the text searching server causes the structure index to be searched for agreement between the context identifiers and the search condition; andwherein the text searching server transmits a text search result to the text searching client upon completion of the search of the structure index.
