Problem when using facet.offset with facet.sort=lex and shards
--------------------------------------------------------------
Key: SOLR-2380
URL: https://issues.apache.org/jira/browse/SOLR-2380
Project: Solr
Issue Type: Bug
Components: search
Affects Versions: 1.4.1, 3.1, 4.0
Reporter: Peter Cline
I'm having a problem using distributed search in conjunction with the
facet.offset parameter and lexical facet value sorting.
I have a facet with ~100k values in one index. I'm wanting to page through
them alphabetically. When not using distributed search, everything works just
fine, and very quick. A query like this works, returning 10 facet values
starting at the 50,001st:
{noformat}http://server:port/solr/select/?q=*:*&facet.field=subject_full_facet&facet=true&f.subject_full_facet.facet.limit=10&facet.sort=lex&facet.offset=50000
# Butterflies - Indiana !{noformat}
However, if I enable distributed search, using a single shard (which is the
same index), I get no facet values returned.
{noformat}http://server:port/solr/select/?q=*:*&facet.field=subject_full_facet&facet=true&f.subject_full_facet.facet.limit=10&facet.sort=lex&facet.offset=50000&shards=server:port/solr
# empty list :({noformat}
Doing a little more testing, I'm finding that with sharding I often get an
empty list any time the facet.offset >= facet.limit. Also, by example, if I do
facet.limit=100 and facet.offset=90, I get 10 facet values. Doing so without
sharding, I get the expected 100 values (starting at what would normally be the
91st).
Thanks,
Peter
