boosting fields when creating index document no longer seems to work in 2.9.*
-----------------------------------------------------------------------------
Key: LUCENENET-370
URL: https://issues.apache.org/jira/browse/LUCENENET-370
Project: Lucene.Net
Issue Type: Bug
Environment: XP VS2010 c#
Reporter: Brett J
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
