Description
There's a race when sending messages while looking at a search view, that clients will try to ask the server whether the message matches search terms after hearing about it. If there's any backlog in fts_update_log, the server may return incorrect results.
From the chat.zulip.org thread:
Options include:
- Checking if any of the messages are in
fts_update_log, and if so, processing them. - Checking if any of the messages are in
fts_update_log, and if so, doing a direct calculation for whether they match. - Something else.
This might be somewhat high priority, since attempts to live-update a search view are fairly likely to trigger this race.
