XF 2.2 No search results after turning off enhanced, falling back to inbuilt, and rebuilding search

[Mouth]

My hosting provider is having an extended hardware issue/outage with the server I have Elastic installled/running, thus search attempts are returning an error and posting is lagging etc.

I have turned off/disabled ES ( /admin.php?enhanced-search/ ) and ran search rebuild for threads ( php cmd.php xf-rebuild:search --type=threads --truncate ) It takes ~1 sec ( I would expect a lot longer for 175K+ threads) and when using search for word(s) in thread titles, even basic words, empty search results is given.

What have I missed?

DB search index table was previously, long time ago, truncated and ES has been active for years. Don't want a full or posts rebuild at this stage into DB, just thought I'd make threads available until ES was available again.

I have turned off/disabled ES ( /admin.php?enhanced-search/ ) and ran search rebuild for threads ( php cmd.php xf-rebuild:search --type=threads --truncate )

Slight syntax issue on the cli parameters, not --type=threads but --type=thread (singular vs plural). So the search rebuild command should be php cmd.php xf-rebuild:search --type=thread --truncate which is now rebuilding as expected.

/admin.php?tools/rebuild leads one to believe it's threads (plural), so I'll submit a bug thread on the no syntax error.

php cmd.php xf-rebuild:search --type=thread --truncate

This gives search results that includes post content, not just thread titles. I had expect only the later when constraining content type.
Is that not the case? What is the difference between thread and post content type when rebuilding search index?
