[jira] Commented: (LUCENENET-350) Performance enhancement in
FastVectorHighlighter
[ https://issues.apache.org/jira/browse/LUCENENET-350?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12846071#action_12846071 ]
Digy commented on LUCENENET-350:
--------------------------------
Hi Bianco,
First of all, could you add a apache licence to the file VectorHighlightMapper.cs?
Your work is very good and pass all tests, but it is not like just a simple bug fix and there is a divergence from FVH java. This makes life hard while making new versions' ports.
All Lucene.Net community!
Any idea about what we should do?

> 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%
