Problem with search engine

If I seach for something I am given the Instruction:

"Search for Keywords:
You can use AND to define words which must be in the results, OR to define words which may be in the result and NOT to define words which should not be in the result. Use * as a wildcard for partial matches"

I cant figure out how to use it, can someone give me a hint?

Congratulations !!

Hello i think the search function is not working properly because using the operators AND OR NOT don't filter the search, for example i search "blowjob NOT pov" and it shows me results with pov keyword, or i use the quotes to search the exact phrase but it shows me results with the keywords i entered but in another order or spread over the description.

search function works properly but all these functions were deprecated long time ago and text of search tips was not fixed
