see 4 tabs one titled GO, then NEW, then FIND, and TOOLS
If you click on FIND you get a little search browser that will pull up any topic that mentions the words you are searching. Like
Heart palpitations or dizziness, or ulcers, or prayers. You name it. It's pretty much all here.
It's been very handy when I was looking up others who have had issues with phobias about driving and so on.
Good Luck
