William, This QParserPlugin should solve that problem now.
Check out https://issues.apache.org/jira/browse/SOLR-1913 BitwiseQueryParserPlugin is a org.apache.solr.search.QParserPlugin that allows users to filter the documents returned from a query by performing bitwise operations between a particular integer field in the index and the specified value. The plugin is available immediately for your use.

To give anything less than your best is to sacrifice the gift. Quality First. Measure Twice. Cut Once. http://www.israelekpo.com/
