Spark 2.9.2 search problem

I used Spark 2.8.3, Spark 2.9.2 and Spark 2.9.3snapshot05/10/2020
No matter how hard I tried to find a person, I could not.
I wrote both ‘’ Hlevnoy Ilya ‘and’ Hlevnoy ‘and’ hlevnoy ’
I couldn’t even find “testuser” and “testuser2” which don’t have a first and last name.

I thought maybe search is disabled on the Openfire server, but no.
