Good afternoon,
Is the f.<field>.facet.mincount option supported on a distributed search?
Under SolrCloud experiencing that some buckets are ignored when using the
option "f.<field>.facet.mincount=1".
The Solr logs do not indicate any error or warning during execution.
The debug=true option and increasing the log levels to the FacetComponent do
not provide any hints to the behaviour.
Replicated the issue on both Solr 4.5.1 & 4.8.1.
Attached a PDF that provides additional details and steps to replicate the
behaviour using the out of the box Solr distribution.
Any insight or recommendation to tackle this situation is much appreciated.
Example,
Removing the f.<field>.facet.mincount=1 option gives the expected list of
buckets for the 6 documents matched.
<lst name="facet_ranges">
<lst name="price">
<lst name="counts">
<int name="0.0">0</int>
<int name="50.0">1</int>
<int name="100.0">0</int>
<int name="150.0">3</int>
<int name="200.0">0</int>
<int name="250.0">1</int>
<int name="300.0">0</int>
<int name="350.0">0</int>
<int name="400.0">0</int>
<int name="450.0">0</int>
<int name="500.0">0</int>
<int name="550.0">0</int>
<int name="600.0">0</int>
<int name="650.0">0</int>
<int name="700.0">0</int>
<int name="750.0">1</int>
<int name="800.0">0</int>
<int name="850.0">0</int>
<int name="900.0">0</int>
<int name="950.0">0</int>
</lst>
<float name="gap">50.0</float>
<float name="start">0.0</float>
<float name="end">1000.0</float>
<int name="before">0</int>
<int name="after">0</int>
<int name="between">2</int>
</lst>
</lst>
Using the f.<field>.facet.mincount=1 option removes the 0 count buckets
but will also omit bucket <int name="250.0">
<lst name="facet_ranges">
<lst name="price">
<lst name="counts">
<int name="50.0">1</int>
<int name="150.0">3</int>
<int name="750.0">1</int>
</lst>
<float name="gap">50.0</float>
<float name="start">0.0</float>
<float name="end">1000.0</float>
<int name="before">0</int>
<int name="after">0</int>
<int name="between">4</int>
</lst>
</lst>
Refreshing the query using the browser's F5 option renders a different
bucket list
(you may need to refresh multiple times)
<lst name="facet_ranges">
<lst name="price">
<lst name="counts">
<int name="150.0">3</int>
<int name="250.0">1</int>
</lst>
<float name="gap">50.0</float>
<float name="start">0.0</float>
<float name="end">1000.0</float>
<int name="before">0</int>
<int name="after">0</int>
<int name="between">2</int>
</lst>
</lst>
