variables.searchphrasepq undefined

Hi all I`ve been working on this for a while now and it has been useful to understand lists and list functions. The following code gets whatever keywords there are on the right(listlast really) of the = delimiter. This works fine for google but no I tried to add a new condition as other search engines use ?p= or ?q= to define string so a string like http://search.msn.com?p=keywords+keywords&int&=N it will get the first in the list after the ?p= not N if that makes sense. I thought I was getting there defining if the string has <cfset findq=find("[p=]|[q=]", qrysales.referer)>
Really I just need a hand please and a push in the right direction-not code just a nod as to what I need to do! Thanks
