Hoss Man created SOLR-3793:
------------------------------

             Summary: duplicate (deleted) documents included in result set when 
using field faceting with fq
                 Key: SOLR-3793
                 URL: https://issues.apache.org/jira/browse/SOLR-3793
             Project: Solr
          Issue Type: Bug
    Affects Versions: 4.0-BETA
            Reporter: Hoss Man
            Priority: Blocker



Günter Hipler reported on the solr-user mailing list that he was seeing 
inconsistencies in facet counts compared to the numFound when drilling down 
onto those facets (using "fq") - in particular: when adding an "fq" such as 
`fq={!term+f%3DnavNetwork}nebis`, the resulting numFound was higher then the 
number of docs reported by the facet constraint for nebis in the base request.

I've been able to trivially reproduce this using the example data from Solr 
4.0-BETA (details in comment to follow)

Important things to note from Günter's email thread with his assessment of the 
problem...

bq. The behaviour is not consistent. Some of the facets provide the correct 
result, some not.  What I can't say for sure: The behaviour was correct (if I'm 
not wrong) once the whole index was newly created. After running some updates I 
got these results.

bq. I'm going to setup a new index with the Lucene 4.0 version from March (to 
be more exactly: it's version 4.0-2012-03-09_11-29-20) to see what are the 
results even in case of frequent updates ... the version deployed in march 
doesn't contain the error I now come across in Beta4.0
