Hi,

We are experiencing a strange problem when wildcards like * and ? are used in the search terms and the results have to be highlighted - the string for the corresponding field is returned empty.

If the highlighter code is removed the results are returned correctly.

Is there a known problem with the highlighter and using wildcards?

Thanks,
Ross

I actually found the answer in the Lucene book. It is in chapter 8.7

The Query.rewrite(IndexReader) method has to be called before passing the Query to the Scorer. This rewrites the queries with wildcards to BooleanQuery of all the matching terms.

Then, everything works fine ...
