I managed to accomplish this using some (hacky and ugly!) javascript. Use the following as your "url":

javascript:url='http://searchengine?term1=%0s&term2=%1s';parts='%s'.replace(/(%5C%5C)?\+/g, function($0,$1)%7Breturn($1?'+':'qzq')%7D).split('qzq');for(var i=0; i < parts.length && (url=url.replace(new RegExp('%'+i+'s', 'g'),parts[i]));i++);location=url.replace(/%[0-9]s/g,'')

I realise this is digging up an old thread, but I just wanted to let sammio5 know how brilliant his javascript hack for multiple search criteria is! I've been well impressed with Chrome since turning to it around 10 months ago, and this trick really adds worth to it. Cheers!

Came up with this solution for this.

Code:

javascript:location='http://yoursite.com/' + '%s'.split(' ')[0] + '/' + '%s'.split(' ')[1] + '.htm'

this will generate http://yoursite.com/argument1/argument2.htm

you can add as many as you want or add anything else that is required to make it populate correctly.

Thats a real nice simple solution and works perfectly hnbc34.
Its great to see a simple solution that I can understand and work with, so thanks.
