Let\'s say I have \"Vegas is great\" in cell A1. I want to write a formula that looks for the exact word, \"gas\" in cells. Vegas ≠ gas, but the only search formula I\'m finding
I think this will handle all the cases that you are planning to handle:
=OR(ISNUMBER(SEARCH(" gas",LOWER(A1), 1 )), LEFT(A1,3)= "gas")
I added a space before the "gas" in the search. And if the gas was the only word in the cell or the first word in the cell, the right part of this function handles that case.
