How do I know how many searches have a specific word?

Hello friends!!

Maybe a basic question here, being a newbie I don't know many things so hopefully I start learning from you guys

How do I know how many searches has a specific word?

Is there a way to know how many searches has the word (for example) "house" in the Playstore or it's impossible?

I'm asking because I'd like to create some game and I want to create one that has the chance to be looked for

Many thanks!!!
