How do I create a search engine that find similar results in case it does not find a specific match? (mongoDB)

Question

I am building a question function in my website where a user can search up a question for example: "how do I cook a cake?" and get a link to the question someone else asked before of whom title is: "how do I make a cake?" the question is almost the same yet the writing is different and for now a user cant find question 2 if they search for question 1 search i just input the search bar into collection.find({}) how do I fix this? is there an API who can maybe generate similar and same meaning sentences to search for?

Thanks!
