Abstract text

A method and apparatus for efficiently processing a query that specifies a location path and a content path is provided. The location path identifies the hierarchical location of a set of documents within a resource hierarchy. The content path identifies hierarchical location of one or more nodes within the content of the set of documents. Computing the query includes using a resource hierarchy index, based on the location path, to generate first results corresponding to the set of documents. Computing the query also includes using a content index, based on the content path, to generate second results corresponding to the one or more nodes. Final results of the query are based on the first results and second results by, for example, joining the first and second results.
