AppleScript "if contain"

I have a script which look for the name and search for a match with a another variable.

It's working fine however if the variable 1 is "Name Demo" and variable 2 is "Demo Name" then the script don't find a match.

set nameMatchTXT to "" if NameOnDevice contains theName then set nameMatch to theName & " : Name Match" end if

Is there anyway to change this to find the match whatever the order ? PS the script is looking for word wild name, and sometime handle dual bit characters which can be a difficulty.
