Hey @neillm I ran a v4 server last week too and the payments weren't being indexed. I thought there was an issue with the catalog code, but didn't get a chance to look at why. In fact, I was thinking it was due to some other problem in the way I was using the multimap, and am in the middle of writing a test to confirm that hypothesis. I have a feeling I am going down the wrong track, but still continuing to see what I discover.
