Subject [jira] [Created] (LUCENENET-505) FastVectorHighlighter create fragment only with match at the beginning
Date Tue, 28 Aug 2012 17:54:10 GMT

             Summary: FastVectorHighlighter create fragment only with match at the beginning
                 Key: LUCENENET-505
             Project: Lucene.Net
          Issue Type: Improvement
          Components: Lucene.Net Contrib
    Affects Versions: Lucene.Net 2.9.4g
            Reporter: Ricci Gian Maria
            Priority: Minor

When you use FastVectorHighlighter fragments returned have the match at the beginning. In
most situation it is much more useful to create fragments with the match in the middle. I've
included a really trivial patch to enable this with a specialized constructor of the SimpleFragListBuilder

Es: FastVectorHighlighter hilighter = new FastVectorHighlighter(true, true, new SimpleFragListBuilder(true),
new SimpleFragmentsBuilder());

The true parameter to SimpleFragListBuilder is named matchInTheMiddle so it has a descriptive
name. Probably it would be useful to create an enum to place the match at: beginning, middle,
