> Key: LUCENE-7551
> URL: https://issues.apache.org/jira/browse/LUCENE-7551
> Project: Lucene - Core
> Issue Type: Bug
> Components: modules/highlighter
> Reporter: Ferenczi Jim
> Priority: Minor
>
> The PhraseQuery contains a list of terms and the positions for each term. The FVH ignores the term position and assumes that a phrase query is always dense. As a result phrase query with gaps are not highlighted at all. This is problematic for text fields that use a FilteringTokenFilter. This token filter removes tokens but preserves the position increment of each removal.
> Bottom line is that using this token filter breaks the highlighting of phrase query that contains filtered tokens.
