Subject [jira] [Commented] (SOLR-4581) sort-order of facet-counts depends on facet.mincount
Date Tue, 09 Apr 2013 15:00:23 GMT

    [ https://issues.apache.org/jira/browse/SOLR-4581?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13626682#comment-13626682
] 

Yonik Seeley commented on SOLR-4581:
------------------------------------

OK, the code from SOLR-3855 had a bug where the IEEE float bits were used/compared directly
for sort order, which is not correct for negative numbers.
I'm testing a patch now, expect to commit shortly.

> I just upgraded to Solr 4.2 and cannot explain the following behaviour:
> I am using a solr.TrieDoubleField named 'ListPrice_EUR_INV' as a facet-field. The solr-response
for the query {noformat}'solr/Products/select?q=*%3A*&wt=xml&indent=true&facet=true&facet.field=ListPrice_EUR_INV&f.ListPrice_EUR_INV.facet.sort=index'{noformat}
> includes the following facet-counts:
> {noformat}<lst name="ListPrice_EUR_INV">
>   <int name="-420.126">1</int>
>   <int name="-285.672">1</int>
>   <int name="-1.218">1</int>
> </lst>{noformat}
> If I also set the parameter *'facet.mincount=1'* in the query, the order of the facet-counts
is reversed.
> {noformat}<lst name="ListPrice_EUR_INV">
>   <int name="-1.218">1</int>
>   <int name="-285.672">1</int>
>   <int name="-420.126">1</int>
> </lst>{noformat}
> I would have expected, that the sort-order of the facet-counts is not affected by the
facet.mincount parameter, as it is in Solr 4.1.
> Is this related to SOLR-2850?
