Performance enhancement in FastVectorHighlighter

                 Key: LUCENENET-350
             Project: Lucene.Net
          Issue Type: Improvement
            Reporter: Bianco Veigel

I've had some performace issues with highlighting large documents (>25MB plain text, >
11000 Terms per Field)

This can be usual if your indexing i.e. log or trace files.
Most of the time is spent loading the field value and stored TermVectors and Offets and itering
over this List.
I've build a TermVectorMapper which filters this List, by the searched terms, so that the
time is reduces by approx. 30%
