title: Validate if the word a is almost same as the word b
body: <p>If you have the string a = "Super rich rush to buy superyachts" and you have the string b = "ruush to buyy".</p>
  
  <p>My question is:
  Is it possible to use regex to make a confirmation if almost all word from the string "a"  is the same from the string "b"? If yes, how?</p>
