> The way the queries are generated now, in many cases the indices are not used when executing
queries.  The main problem is that gremlin cannot currently use "has" expressions within an
"and" or an "or".  This JIRA introduces a GremlinQueryOptimizer that attempts to extract "has"
expressions out of "and" expressions and turn "or" expressions into unions.
