FastVectorHighlighter.Net returning null on GetBestFragment

Question

Hi

I have a large index, on which Highlighter.Net works fine, but FastVectorHighlighter returns null as a Best Fragment on Some documents.

the searcher works fine. It is just the highlighter. The field has been indexed in the same manner for all documents, so I fail to understand Why it highlights some documents but not all.

Using Lucene.Net 2.9.2, built from trunk rev942061

Answer 1

are you setting FieldMatch to true?

Answer 2

Problem solved by the nice people at lucene-net-user. I was passing the document sequence number in the Hits object, where I should have been passing the sequence number in the lucene index. Read full mailing list thread starting here
