Many thanks for your response Otis - I had feared as much, but it's good
to have it confirmed.
Best wishes,
Daniel

Hi,
I think nobody in the community is focused on field
collapsing/grouping, so I suspect there won't be a fix until somebody
gets a strong-enough itch or business requires it so much that it
decides it pays to invests in the contribution.

Hi everyone,
I'm seeing very bad performance when grouping (field collapsing) using
group.facet=true with a large result set.
- I have an index with 2 million documents, and I query with five facet
fields (each with 30+ groups)
- If I set group.facet=false the query can take 2000ms on first run, but no
more than 250ms on subsequent execution
- If I set group.facet=true it takes on average 18000ms on the first run,
and the same time on all subsequent runs (suggesting to me that a cache is
not being used)
I've checked the Solr Jira and several others are experiencing the same
issue:
https://issues.apache.org/jira/browse/SOLR-4763
Could anyone offer any advice or suggestions please? This is becoming a
blocking issue for us, and I'm very curious if this will be fixed in the
near future?
Best wishes,
Daniel
