A system for storing and retrieving text-based documents stores each of the documents in accordance with a mark-up language that comprises mark-up elements defined by a meta-language such as XML (Extensible Mark-up Language). In particular, each text document includes a plurality of text items, and each text item is associated in the text document with at least one of the mark-up elements. Each text document is stored at a central repository that is in communication with a plurality of user computers. A user can retrieve those documents that are of interest by formulating a search query that is transmitted from a user computer to the central repository. A search engine searches through the text items of each stored text document in order to determine which text documents satisfy the search query. Those text documents that satisfy the search condition are retrieved from the central repository and provided to the user computer for display.

L'invention concerne un système de stockage et de récupération de documents textuels qui stocke chaque document conformément à un langage hypertexte qui comprend des éléments hypertextes définis par un métalangage comme XML (langage de balisage extensible). En particulier, chaque document textuel inclut plusieurs éléments textuels, et chaque élément textuel est associé dans le document textuel à au moins un des éléments hypertextes. Chaque document textuel est stocké dans un dépôt central qui est en communication avec plusieurs ordinateurs d'utilisateurs. Un utilisateur peut récupérer les documents intéressants en formulant une demande de recherche qui est transmise de l'ordinateur d'un utilisateur au dépôt central. Un moteur de recherche cherche dans les éléments textuels de chaque document textuel stocké pour déterminer quels documents textuels répond à la demande de recherche. Les documents textuels qui répondent à la condition de la recherche sont récupérés dans le dépôt central et fournis à l'ordinateur de l'utilisateur pour être affichés.
