Summary:
Ref T9979. There are currently some hacks around Conpherence indexing: it does not really use the fulltext index, but its own specialized index. However, it's kind of hacked up so it can get reindexed by the normal indexing pipeline.
Lift it up into IndexEngine, instead of FulltextEngine. Specifically, the new stuff is going to look like this:
- IndexEngine: Rebuild all indexes.
- ConpherenceIndexExtension: Rebuild thread indexes.
- ProjectMemberIndexExtension: Rebuild project membership views.
- NgramIndexExtension: Rebuild ngram indexes.
- FulltextIndexExtension / FulltextEngine: Rebuild fulltext indexes, a special type of index.
- FulltextCommentExtension: Rebuild comment fulltext indexes.
- FulltextProjectExtension: Rebuild project fulltext indexes.
- etc.
Most of this is at least sort-of-in-place as of this diff, although some of the part in the middle is still pretty rough.
Test Plan:
- Made a unique comment in a Conpherence thread.
- Used `bin/search index --force` to rebuild the index.
- Searched for the comment.
- Found the thread.

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.
