I've wanted to make a search engine string to use with Biblia. I couldn't get anything to work from the main window, but I did get something to work in relation to a plain bible search.
With Opera I got this:
http://biblia.com/books/esv/resolve?input=%s
To run it using Glims with Safari on the Mac one simply changes the %s to #query#
If one wants to make it for some other Bible, use the letters for that translation.
