/**
* Applies a filter against the title field in elasticsearch. When not negated
* the term remains in the original query as a scoring signal. The term itself
* is used as a QueryString query, so some advanced syntax like * and phrase
* matches can be used. Note that quotes in the incoming query are maintained
* in the generated filter.
*
* Examples:
* intitle:Foo
* intitle:Foo*
* intitle:"gold rush"
*
* Things that might seem like they would work, but don't. This is because the
* quotes are maintained in the filter and in the top level query.
* intitle:"foo*"
* intitle:"foo OR bar"
