Membership, controlling search page

I am having trouble allowing the search page to work for members. When I set up URL groups for search my whole site goes kaflooey. Is there a trick to using url groups to allow search page access for members? I have tried a few regular expressions, and have tried strip query on and off, but so far have had no luck.

A couple things to note: I am successfully using an URL group to control access to a custom post type by making a negative rule and using a regex to block all posts beyond a certain directory.

Search works for a couple of random words like blog or hello, but other single words that should also come up dont. And, all two letter words fail to find anything.

Under an admin account search works perfectly in all cases.
