Hi all,
I'm using highlighter with TermQuery and RegexQuery and everything works
well.
As soon as I try to use IntervalQuery, the highlighter returns no fragment.
Does someone know if IntervalQuery is supported with Highlighter /
QueryScorer?
Thanks,

should work?
When I use a WildcardQuery with the highlighter, I don't get any fragments
back, I get null returned to strBetText. If I just use a term query then it
works.
TokenStream tokenStream = TokenSources.getTokenStream(indexReader, docId,
strFieldName);
QueryScorer scorer = new QueryScorer(
Yep that was it :-)
Thanks !

Are you sure you imported Highlighter from the correct lucene
Are you sure you imported Highlighter from the correct lucene namespace
org.apache.lucene.search.highlight.Highlighter
and not something else like javax.swing.text.Highlighter?

I'm trying to get the highlighter running, but didn't get it work.
Everywhere it's posted as following:
Highlighter highlighter = new Highlighter(new SimpleHTMLFormatter(),
new QueryScorer(query));
but that gives me a
"Highlighter is abstract; cannot be instantiated".
changing MultiTermRewriteMethod fixed all previous incompatibility issue.
After setting this:
myQueryParser.setMultiTermRewriteMethod(MultiTermQuery.SCORING_BOOLEAN_QUERY_REWRITE);
highlighter get compatible with rewrite, query.rewrite().toString() works as
before and scoring works fine for
OK, to answer my own question:
I found from the following issue that if I do a query.rewrite(), highlighter
doesn't work.
https://issues.apache.org/jira/browse/LUCENE-1425
I did rewrite() in order to find all matched terms for example in a prefix
query, but as this doesn't work an
1 - 100 of 274 matches
