if you want the search fields to be blank, you would just pass the search fields using url variables and set them as blank. For example, I have a search for products and if I click search without anything filled in to the search, the url looks like this:
Products_Results.php?S_ProductName=&S_ProductPrice=&S_ProductPrice2=&Search=Search
You can try this the same with your page and just use that url to link people to the page initially.
