The problem comes from this method: org.apache.lucene.search.highlight.WeightedSpanTermExtractor.extract(Query, Map<String, WeightedSpanTerm>)
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 extracted. It this a bug? Thanks, Mohsen Mohsen Saboorian wrote: > > Yes I can (though I need some time, since I have my nested custom > analyzers and filter).
