Hi Brett,
Have you tested Lucene.Net 2.9.X using
*queryParser.SetMultiTermRewriteMethod(MultiTermQuery.SCORING_BOOLEAN_QUERY_REWRITE)*
?

> Hello,
> there seems to be an issue with boosting document fields in 2.9.*.
> If I switch the lucene DLL back to 2.4.0.2 it works fine, but when I change
> to 2.9.* or above, the boost no longer seems to have an effect on the query
> results.
> i.e
> Field fldContent = new Field("f1", value, Field.Store.YES,
> Field.Index.ANALYZED);
> fldContent.SetBoost(1000)
> Field fldContent = new Field("f2", value, Field.Store.YES,
> Field.Index.ANALYZED);
> fldContent.SetBoost(1)
> A prefix query searching both f1 and f2 should always return f1 matches with
> a higher score and at the top of the results, this seems to be broken in
> 2.9.*.
> If you add the boost to the query itself and not the field it works
> correctly, but this is slower and we want to avoid it.
> We had to downgrade back to 2.4.0.2 to get around the issue
> cheers
> Brett
