Solr 3.4 group.truncate does not work with facet queries
Hi, I'm using Grouping with group.truncate=true, The following simple facet
query:
facet.query=Monitor_id:[380000 TO 400000]
Doesn't give the same number as the nGroups result (with
grouping.ngroups=true) for the equivalent filter query:
fq=Monitor_id:[380000 TO 400000]
I thought they should be the same - from the Wiki page: 'group.truncate: If
true, facet counts are based on the most relevant document of each group
matching the query.'
What am I doing wrong?
If I turn off group.truncate then the counts are the same, as I'd expect -
but unfortunately I'm only interested in the grouped results.
- I have also asked this question on StackOverflow, here:
http://stackoverflow.com/questions/7905756/solr-3-4-group-truncate-does-not-work-with-facet-queries
Thanks!

Thanks, Marijn. I have logged the bug here:
https://issues.apache.org/jira/browse/SOLR-2863
Is there any chance of a workaround for this issue before the bug is fixed?

Hi Ian,
I think this is a bug. After looking into the code the facet.query
feature doesn't take into account the group.truncate option.
This needs to be fixed. You can open a new issue in Jira if you want to.
