------------------------------------
Summary: Facet offset not returning enough results with solr cloud
Key: SOLR-10642
URL: https://issues.apache.org/jira/browse/SOLR-10642
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrCloud
Affects Versions: 6.4.1
Reporter: Sascha Markus
A collection has four shards.
A field has >5K terms according to the web ui for one core of the collection.
A json facet query with limit 20 and offset 0 returns 20 buckets as expected.
The same query with an offset of 20 returns only seven more buckets.
With debugQuery= true I see that the first query with offset = 0 the four
cores return 27 different vals which are merged. The top 20 are collected for
the result.
With offset=20 I see the same 27 vals for the cores. But now the first 20 are
skipped and seven are returned.
And with offset=40 the same is returned as for offset=20.
Example:
http://mysolrserver/solr/my_collection/select?wt=json&indent=false&q=*&rows=0&json.facet={"my_facet"%3A+{"field"%3A+"some_field"%2C+"limit"%3A+20%2C+"offset"%3A+20%2C+"sort"%3A+"count+desc"%2C+"type"%3A+"field"}}
