For example in template andy_similarthreads_below_quick_reply
remove strings
<th>{xen:phrase date}</th>
and
<td>{xen:datetime $similarThread.post_date}</td>
and save template.
unfortunately is no
WHERE xf_thread.title LIKE " . XenForo_Db::quoteLike($searchWord1, 'lr') . "
AND xf_thread.title LIKE " . XenForo_Db::quoteLike($searchWord2, 'lr') . "
Module use mysql like search.
@RoldanLT where you found the using of ES?
Maybe this problem is related to cookie xf_session?
Alternatively, you can set Session.php SearchReferer and isRobot required expiration lifetime and use these value in nginx
