Summary: Ref T3165. Builds a dedicated index for Conpherence to avoid scale/policy filtering concerns. - This is pretty one-off but I think it's generally OK. - There's no UI for it. - `ConpherenceFulltextQuery` is very low-level. You would need to do another query on the PHIDs it returns to actually show anything to the user. - The `previousTransactionPHID` is so you can load chat context efficiently. Specifically, if you want to show results like this: > previous line of context > **line of chat that matches the query** > next line of context ...you can read the previous lines out of `previousTransactionPHID` directly, and the next lines by issuing one query with `WHERE previousTransactionPHID IN (...)`. I'm not 100% sure this is useful, but it seemed like a reasonable thing to provide, since there's no way to query this efficiently otherwise and I figure a lot of chat might make way more sense with a couple of lines of context. Test Plan: - Indexed a thread manually (whole thing indexed). - Indexed a thread by updating it (just the new comment indexed). - Wrote a hacky test script and got reasonable-looking query results.
