I haven't really been following this conversation that closely, but assuming what you guys are talking about is desirable, it seems like one way to accomplish it might be to make it operate on the *indexed* values for a field
Yes, the current JIRA patch uses the FieldCache.
... wouldn't iterating over each doc, and using the FieldCache+TermDocs make it very efficient to find all the docs that have the same indexed value as the current one?
The most efficient way will heavily depend on the nature of the collapse field (few terms or many). I can't currently think of a way to do it efficiently for both. -Yonik
