How to use IF(ISERROR(FIND))) to search multiple cells in one row

[theasianova]

=IF(ISERROR(FIND("letter of credit",OR(O16,P16),1))=TRUE,"NO","YES")

I tried to use OR(O16,P16) to get the formula to search for both O16 and P16 to check if either cell contains "letter of credit."

The original formula works:
=IF(ISERROR(FIND("letter of credit",O16,,1))=TRUE,"NO","YES")

where this only searches one cell O16.

Are there other ways to construct this keyword search?

Try this version

=IF(COUNT(FIND("letter of credit",O16:P16)),"YES","NO")
