With HeroHunt.ai there is no longer any necessity for boolean searches. In fact, HeroHunt.ai automatically includes synonyms for keywords as it is searching for your best matches.
HeroHunt.ai also prioritises keywords automatically in 'Required keywords' and 'Nice to have' keywords. All of the required keywords or its synonyms always have to be on a profile for it to appear in your best matches, but 'Nice to have' keywords don't have to be on a profile for it to appear in your best matches.
You can drag and drop the keywords from Required to Nice to have if you want to change the priority of those keywords.
