This is certainly something we would like to offer our site users. At this time however it's been difficult to setup because we don't always obtain information that people wish to search for by keyword - things like waterfront , golf course view, 3-car garage and so forth.
We are always evolving though and I'm sure that we'll offer a keyword search in the future. Bottom line is that we want to wait until we're sure that we can deliver great results.
If you have other suggestions for us I encourage you to access the link below and send them to us.
