Is there a simple formula for checking if a cell contains a text string,
which returns a TRUE/FALSE? It is possible to combine  "ISERROR" and "FIND",
but this becomes a pain when you have to do it all the time.  Instead of
using the reverse logic of:

=if(iserror(find("text",A1))=FALSE,...

it would be so much easier to write:

=if(contains("text",A1),...

This is a very basic thing you can do with an autofilter, so it seems like
there would be a function that does this without returning error values.  Any
suggestions?  Thank you.
