Subject [jira] Commented: (SOLR-1682) Implement CollapseComponent
Date Thu, 30 Sep 2010 12:24:41 GMT


Jasper van Veghel commented on SOLR-1682:

Great stuff guys. We're using Field Collapsing to fold in URLs of documents in our index which
have the same URL but multiple individual content parts. We can't merge these earlier in the
indexing proces as each individual page content-part has different access rights. As such,
not every piece of content is accessible to everyone, but different users with different access
rights might still end up on the same URL and might end up finding multiple results for the
same page URL.

As for faceting and highlighting - I've managed to merge in the faceting patch from SOLR-2098
and have taken the highlighting changes from Yonik's github commit (r997870). This seems to
be working flawlessly, and all we're rooting for now is for some love for distributed collapsing
so we use it across multiple shards. So far we haven't run into any issues with the current
(august 20th) patch. Keep up the good work!
