LUCENE-9133 Fix for potential NPE in TermFilteredPresearcher#buildQuery
> TermFilteredPresearcher NPE issue with empty fields
> ---------------------------------------------------
>
> Key: LUCENE-9133
> URL: https://issues.apache.org/jira/browse/LUCENE-9133
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Marvin Justice
> Priority: Major
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> Encountered a situation where a document contained a field value which
> analyzed away to nothing. The result was a NPE in
> TermFilteredPresearher#buildQuery. We filter out purely empty fields before
> creating the Document for Monitor#match but it's hard to know up front when
> a non-empty field will produce zero tokens after analysis. Will follow up
> with a PR containing a simple unit test that triggers the NPE along with a
> proposed fix.
