Is there any Lucene highlighter that does not requ

Question

I have been reading the new 2nd edition of the Lucene in Action and they give an example of doing highlighting but unfortunately it requires the original text so it can get the position of terms etc. The highlighter is the official one in contrib, so that implies its the sponsorted or official highlighter.

Does anyone know of another highlighter that does not require the original text but works using the term positions (sorry if i got the terminology wrong) ???

Answer 1

Both the standard highlighter and FastVectorHighlighter can use the index if you store the terms. (FVH can only use the index, in fact). You can see an example of this on page 274 of Lucene in Action. The relevant code line is:

TokenStream stream = TokenSources.getAnyTokenStream(searcher.getIndexReader(), sd.doc, "title", doc, analyzer);

That will get the token stream from the index.
