Oops, sorry. I didn't see your second post before I wrote mine. You are correct, it would open that link if you compiled it like that (and packaged it or installed it). But making a plugin for each search provider is probably not a good choice. I'll try to make one plugin take care of all search providers, with an easy option to create custom searches as well. Would it be sufficient if you could click a button and then select the search provider of choice?
