Multiple parameter keyword searches in firefox (or chrome)

I love using firefox's (and chrome's) custom keyword searches. One lookup I often do is a company directory using people's first and last names. I was wondering if I could substitute 2 parameters like this:

http://internal.mycompany.com/directorySearch?fname=%s&lname=%s (this is a fake url)

so I could do a lookup like this

That is exactly what is described here: http://kb.mozillazine.org/Multiple_parameter_keyword_searches

However, it doesn't seem to work for me. Can someone either confirm that the instructions in the above link do work (and that I somehow fumbled them) or let me know if there's another way to do it?

Thanks!

ps - if you know a way to do this in chrome, please share that as well.

Yes, it is possible in Chrome!

I managed to create a really cool search engine for subtitles. I just type: subs <title> <season> <episode> and automatically go to the downloadpage for the episode i want. You could even add language parameters or more.

Just add this javascript as the URL in chrome://settings/searchEngines:

javascript:url='http://www.podnapisi.net/nl/ppodnapisi/search?sT=1&sK=%0s&sTS=%1s&sTE=%2s';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,'')
