Did you have the Multi Prefix add-on installed, previously? If so, that's the cause for this.

That add-on will require an update before being able to rebuild the search index.

It looks like all legacy add-on data was deleted, and @Adam Dicker upgraded from XF1.x to XF2.x with a older version of Multi Prefix which didn't support XF2.

This makes troubleshooting challenging. I should have some SQL which can discard multiple prefixes to restore search, but Multi Prefix for XF2 is still on my to-do list.

The following should remove all multiple prefixes picking the first to keep.


Run each statement one after the other.

Please ensure you have a database backup, or at least clone the xf_thread table somewhere as this is a destructive operation and this SQL is provided as-is and is a best effort.

SQL:
UPDATE xf_thread
SET prefix_id=IF(LEFT(prefix_id,LOCATE(',',prefix_id) - 1) != '', LEFT(prefix_id,LOCATE(',',prefix_id) - 1), prefix_id);
where prefix_id like '%,%';

UPDATE xf_thread
SET prefix_id = '0'
WHERE prefix_id = '';

alter table xf_thread prefix_id INT UNSIGNED NOT NULL DEFAULT 0;
