If Cell In Column Partially contains text in another Column

Question

I have been looking through all different sources and cannot find the exact answer to this. Was hoping someone can help me out.

I have two columns:

Answer 1

To do it for full columns as real non-array formula:

=COUNTIF(B:B,"*"&A1&"*")>0

Answer 2

This will do it:

=SUMPRODUCT(ISNUMBER(SEARCH(A1,$B$1:$B$4))*1)>0

The SUMPRODUCT() forces it to iterate through Column B and keep track of the ones that return true. So if any are found it adds 1 to the pool.

The >0 test whether any returned TRUE.
