title: Detect a string in several cells of Google Sheets
body: <p>I'm using this formula to detect a string in a specific cell of my Google Sheet.</p>
  
  <pre><code>=IF (REGEXMATCH('Mysheet'!GE2;"yes");"X";"O")
  </code></pre>
  
  <p>But now I want to verify if I can find that string "yes" in three other cells at the same time GF2,GH2,GI2. How to do that?</p>
