Hiya, jbear6. Thank you for installing.
Well, i've been at this for about 20 minutes, and Jesus, this one is tough!
One thing has hasn't helped is that websites Java Servlet approach! It's rather slow and prone to being very un-helpful when trying to "hack" it.
I can't seem to manage to get the output fully. But I have managed the following :
http://www.merckvetmanual.com/mvm/servlet/CVMSearch?searchType=0&searchSubType=-1&startIndex=0&numResults=10&hilightTerm=null&quer yText=
... put that as your search URL, and it should work. But, the whole website design won't show, only the results.
If that will do, then bless you.
