Answer 1

when I make a request with LIKE , I get a larger number of selections than I do the same with regexp, how is it?
Why do you think that you have the same mask? She is completely different.
The value for REGEXP is designed so that only exact matches are searched.
For example, if your "desired_profession" field has the value "physician", then it will fall under your LIKE condition, but will not fall under your regular expression.
But the value "doctor" will fall under both conditions.
REGEXP '.*врач.*'
