Variables search engine does not search for the fields I have added in the collections

As in the topic name. If I want to search for a field in variables, the search engine does not work properly. I cannot search for the value I am looking for among multiple variables, e.g. among the fields I have added in collections.

All the variables show up for me every time, even if I click enter the search engine doesn’t work

I would like to ask for your help
