can anyone help me match results by words in elasticsearch regex? I am new to regex.

If I have strings as per below :

  • string 1: "Hello, are you fine?"
  • string 2: "Does she use youtube?"

If I search for "you" word in elastic search then I want just "string 1" as an output. and If I search for "are you" then it should also give me a "string 1" as an output.

I tried with below regex but not giving me the expected output :

  • pattern 1: ".*you.*" - it's giving me both string as an output.
  • pattern 2: "/\syou\s/" - it's not giving me an nay output.

Can anyone help me to fix this ?

    Did you try with `/\byou\b/` ? – EricLavault Jan 08 '20 at 13:37
  • @EricLavault I tried with /\byou\b/ but it's not working. :( – Yellow Digital Labs Jan 08 '20 at 13:52
  • Please post your full search query. Are the quotation marks actually part of your strings and/or search patterns? – BadHorsie Jan 08 '20 at 13:55
