MULTIFACETED SEARCH

摘要

A query is received that includes two or more facets of a multidimensional inverted index for a collection of documents. Each document is associated with at least one facet. Generation of the multidimensional inverted index includes creating one or more entries. Each entry includes a combination of two or more facets and a posting list of indications for the documents associated with respective facets of each entry. Each indication identifies a document. Generation of the index also includes determining documents associated with respective facets of the combination of each entry. The multidimensional inverted index is searched for an entry having the combination of two or more facets included in the query and a search result is returned. An indication for a document may be included in a posting list if it is determined that the document is associated with each facet of the combination of facets of the entry.
