I like Rink.Attendant.6 answer. I actually want to check for multiple strings and did it this way:
First the situation: Names that can be home builders or community names and I need to bucket the builders as one group. To do this I am looking for the word "builder" or "construction", etc. So -
=IF(OR(COUNTIF(A1,"*builder*"),COUNTIF(A1,"*builder*")),"Builder","Community")
