After updating to 2.9.x or 3.0, highlighter doesn't work on wildcard queries
like "abc*". I thought that it would be because of scoring, so I also set
myIndexSearcher.setDefaultFieldSortScoring(true, true) before searching.
I tested with both QueryScorer and QueryTermScorer.

Yes I can (though I need some time, since I have my nested custom analyzers
and filter). I'll try to write a test scenario to reproduce this issue.
For now, can you tell me if these steps are correct for instantiating and
using highlighter:
IndexSearcher is = new IndexSearcher(indexReader);
Quer
The problem comes from this method:
org.apache.lucene.search.highlight.WeightedSpanTermExtractor.extract(Query,
Map)
The query passed to this method is of type
org.apache.lucene.search.ConstantScoreQuery, but it matches non of
'instanceof' checkings in this method, so no WeightedSpanTerm is extra
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 anymore like Lucen
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 wildc
