How can you test the work of the search engine for the correctness of the results it produces?

Question

Software testing

Greetings.
Tell me, what is the best way to test the search for the correctness of the results?
Why did the question arise?
There will always be one of the users who will definitely catch the next bug and this is not entirely satisfactory. I would like to eliminate all the shortcomings in advance to the maximum on my own.
Are there checklists, test cases or workflow algorithms that can be used to test the correctness of the search results and the operation of the search algorithm as a whole in order to be sure that the logic of its work is correct?
It is necessary to clearly grasp the line between:
“I should have found it here, but I didn’t find it - this is a bug”
and
"here is a strange result, although, indeed: how could he guess that this is what the request is about? - this is not a bug"
(maybe there are ready-made tools?....)
You need to test here .
Thanks in advance.
