> 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%
