Reporter: Andreas Müller
Our setup is based on multiple cores. In One core we have a multi-filed with
integer values. and some other unimportant fields. We're using multi-faceting
for this field.
We're querying a test scenario with:
{code}
http://localhost:8983/solr/core-name/select?q=dummyask: (true) AND
manufacturer: false AND id: (15039 16882 10850
20781)&fq={!tag=professions}professions:
(59)&fl=id&wt=json&indent=true&facet=true&facet.field={!ex=professions}professions
{code}
- Query: (numDocs:48545, maxDoc:48545)
{code:xml}
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">1</int>
</lst>
<result name="response" numFound="4" start="0">
<doc>
<int name="id">10850</int>
</doc>
<doc>
<int name="id">16882</int>
</doc>
<doc>
<int name="id">15039</int>
</doc>
<doc>
<int name="id">20781</int>
</doc>
</result>
<lst name="facet_counts">
<lst name="facet_queries"/>
<lst name="facet_fields">
<lst name="professions">
<int name="59">4</int>
</lst>
</lst>
<lst name="facet_dates"/>
<lst name="facet_ranges"/>
<lst name="facet_intervals"/>
<lst name="facet_heatmaps"/>
</lst>
</response>
{code}
- Then we update one document and change some fields (numDocs:48545,
maxDoc:48546) *The number of maxDocs is increased*
{code:xml}
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">1</int>
</lst>
<result name="response" numFound="4" start="0">
<doc>
<int name="id">10850</int>
</doc>
<doc>
<int name="id">16882</int>
</doc>
<doc>
<int name="id">15039</int>
</doc>
<doc>
<int name="id">20781</int>
</doc>
</result>
<lst name="facet_counts">
<lst name="facet_queries"/>
<lst name="facet_fields">
<lst name="professions">
<int name="59">5</int>
</lst>
</lst>
<lst name="facet_dates"/>
<lst name="facet_ranges"/>
<lst name="facet_intervals"/>
<lst name="facet_heatmaps"/>
</lst>
</response>
{code}
*The Problem:*
In the first query, we're getting a facet count of 4, which is correct. After
updating one document, we're getting 5 as a result wich is not correct.
