Falkon browser startpage search does not work

Installed Falkon browser and noticed when I search with startpage it just redirects me to startpage homepage.  Played with the URL and postdata settings some and it just kept doing the same thing.  Even if I used a format that worked in Firefox the same thing would not work in Falkon.  Eventually I got this format to work for using Falkon and startpage as the default search engine.
