I need help with the FDSE's search engine. I got it installed and everything works fine, but I wanted to know how to code it if I want something like an advance search engine. I read the 'Help' menu on the said search engine, but I still don’t get it plus I don’t want to make the whole thing go haywire. The things I wanted to include are below:

Shophouse or house (I'll be using the radio box thingy)
Rent or Sale (another radio box)
Location (drop-down menu)
Price range (drop-down menu)

So anyone knows how?

How is the coding if I want the search engine to look for more than one term like make the search more specific? There will be this drop-down menu and the radio box thingy where people can choose from : shophouses or houses to price range and bla bla bla. So anyone?

I did some trial and errors like giving the name for each boxes and drop-down menu the same name: Terms. I update the meta tags for each page ... but everytime I try out the search engine it will give me the result of all 43 pages. Anyone?

Sorry I cannot seem to find any 'EDIT' button. Anyway here is how I code the searh form (well parts of the coding):
