ABSTRACT:
Techniques for efficiently processing a query are provided. A query may specify a location path and a content path. The location path identifies the hierarchical location of a set of documents within a resource repository. 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 repository index, based on the location path and the content path, to generate first results corresponding to the set of documents and second results corresponding to the one or more nodes. Final results of the query are based on the first results and second results. Another technique is provided for formatting a locator value in the repository index to support data that is stored object-relationally. Another technique is provided for storing index information about virtual content.
