I think you ment IS a multiple of 2, as he wants the data compared not the itemnames.

Funny thing was i was going to say that myself, well something like it, i actually wrote it down, then reread his request and picked up hes just doesnt understand how to use $hfind

I also just thought, considering we know what he wants to do, just be listed the resulting matches. so...
/hsave -on hashtable tempfile.txt
/filter -ffc tempfile.txt tempfile.txt matchtexthere
/play -n $nick tempfile.txt

that should work.
