Hi Deb and welcome to our forum,
You can use your own rules, buttons, and query adapters to customise the experience. I'm not sure why your forum is switching to the other view, but it may have something to do with the rules around the existing Search button. Go to Designer, double click on Search. Click on Rules to see if there are any rules. If not, check to make sure the form doesn't have any code.
