------------------------------------
Help!!
We've been using this patch in production for months now, and suddenly in the
last 3 days it is crashing constantly.

It seems to happen randomly - there's no special request happening, nothing new
added to the index, nothing. We've made no configuration changes. The only
thing that's happened is more documents have been added since then. The schema
is the same, we have perhaps 200000 more documents in the index now than we did
when we first went live with it.
It was a 32-bit machine allocated 2GB of RAM for Java before. We just upgraded
it to 64-bit and increased the heap space to 3GB, and still it went down last
night. I'm at my wits end, I don't know what to do but this functionality has
been live so long now it's going to be extremely painful to take it away.
Someone, please tell me if there's anything I can do to save this thing.

> This patch include a new feature called "Field collapsing".
> "Used in order to collapse a group of results with similar value for a given
> field to a single entry in the result set. Site collapsing is a special case
> of this, where all results for a given web site is collapsed into one or two
> entries in the result set, typically with an associated "more documents from
> this site" link. See also Duplicate detection."
> http://www.fastsearch.com/glossary.aspx?m=48&amid=299
> The implementation add 3 new query parameters (SolrParams):
> "collapse.field" to choose the field used to group results
> "collapse.type" normal (default value) or adjacent
> "collapse.max" to select how many continuous results are allowed before
> collapsing
> TODO (in progress):
> - More documentation (on source code)
> - Test cases
> Two patches:
> - "field_collapsing.patch" for current development version
> - "field_collapsing_1.1.0.patch" for Solr-1.1.0
> P.S.: Feedback and misspelling correction are welcome ;-)
