Subject [jira] [Commented] (SOLR-2689) !frange with query($qq) sets score=1.0f for all returned documents
Date Wed, 03 Aug 2011 00:10:27 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2689?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13078522#comment-13078522

Hoss Man commented on SOLR-2689:
--------------------------------

I don't really understand why this is a bug?

"frange" is the FunctionRangeQParserPlugin which produces ConstantScoreRangeQueries -- it
doesn't matter when/how/why it's used (or that the function it's wrapping comes from an arbitrary
query), it always produces range queries that generate constant scores.

document digest and score (i don't seem to be able get only score, fl=score returns all fields):

> This query uses frange with query() to limit the number of returned documents. When using
multiple search terms i can indeed cut-off the result set but in the end all returned documents
have score=1.0f. The final result set cannot be sorted by score anymore. The result set seems
to be returned in the order of Lucene docId's.
