Where to find a list of Google search operators?

Question

I heard once that there are some search keywords or operators that google could use to enhance the search results. One of them was "NEAR"...

Say if I search

"make" NEAR "great again" 

it would search pages with "America" or (more recently "France":), but not the pages entited "Make Cookies" and where there is a comment in the bottom of the page "great again to see you, Steve!"

My question is how to know if that keyword is or not used, maybe it was removed, cause doesn't seem to work actually. Is there anywhere more or less official list of Google search help keywords?

Answer 1

Thanks to the @pritaeas comment, here I found out I can use instead of NEAR, the * wildcard.

So, the upper search that works now should be like this:

"make * great again"
