WOW! Thanks to you all!!! I have not completely tested it, but so far it
seems to work beautifully!
You were right... there was no misunderstanding!
Thank you so much!!

No, Peo only got the string order wrong. Change his formula to

=SUMPRODUCT(--(X2:X40000="warranty"),
--ISNUMBER(SEARCH("switch",AD2:AD40000)))

and it will produce the result you claim to be seeking. The
ISNUMBER(SEARCH(..)) idiom is the STANDARD approach to indicating
whether a substring exists in a longer string, though, FTHOI, this
could also be done with (SUBSTITUTE(string,substring,"")=string) less
efficiently (sometimes only one level of function calls is necessary).
