Websearch allows you to create keyword searches based upon the Firefox "add a keyword search" type string. Then the app will allow you to enter the search string, and it loads Safari with the search page.
Websearch comes preloaded with several common search engines but you can add/remove/resort on your own using the built in GUI.
NOTE: Websearch can be installed a lot easier if you will use Installer or Cydia to be sure its functions are not crippled in any way. Also, in case you need it, you can find support for Websearch on the developer's website.
