The how has been explained - but I warn you it is hopeless!!! I get better results by using google and including HealthUnlocked in the search!
If you do try the HU search you will find you get totally unrelated options that just happen to include one word you searched for - and tens of thousands of them from all over HU at that. You can narrow the search to your own communities and even to one community which does at least cut the number down but I have searched for a particular post for which I knew the exact title and it couldn't find it using HU search!
