Abstract
A search engine system accepts queries that include query terms and labels applicable to certain documents. A domain filter is constructed that is used to filter search results to certain domains, where the domains are determined based on the labels included in the query. The filtered search results are processed to ensure that certain portions of the results are from domains included in the filter. The results are further processed to include the query labels with certain ones of the results.
