Search the words I actually want

How do I get the search function to search only the words I want?
I’ve tried “putting the words I want in quotes” and only using single words.
I still get results which have part of the word I’m looking for as well as the actual word.
How do I stop getting results I don’t want?

Can you show some screenshots of examples? We support quote searches, so if you’re adding quotes you should only get exact matches.
