Counting partial strings

I don't know what's wrong with this it's not working..


=COUNTIF(SEARCH("radio",A2:A20),"")


i just want to count all the cells from a2 to a20 that has a word "radio" from that cells. Since a2 until a20 have different words like tv power, radio blaster (this should be consider because there's a radio word on it) and so on.


if i use only =COUNTIF(A2:A20,"radio") the word should be exact "radio" and it wont consider the word "radio blaster".

someone? I'm starting to teach myself with codings, but also starting to encounter some problems, lolz..


Thanks!

Try

=Countif(A2:A20,"*radio*")
