Abstract: front page image
(EN)An information retrieval system uses phrases to index, retrieve, organize and describe documents. Phrases are identified that predict the presence of other phrases in documents. Documents are the indexed according to their included phrases. The document index is partitioned into multiple indexes, including a primary index and a secondary index. The primary index stores phrase posting lists with relevance rank ordered documents. The secondary index stores excess documents from the posting lists in document order.

Les expressions qui prévoient la présence d'autres expressions dans des documents, sont identifiées. Des documents sont indexés selon les expressions qu'ils contiennent. L'index du document est subdivisé en multiples index comprenant un index primaire et un index secondaire. Dans l'index primaire figurent des listes de consignation d'expressions avec des documents ordonnés suivant leur degré de pertinence. Dans l'index secondaire figurent des documents en excès des listes de consignation, dans l'ordre des documents.
