Forum What is the parameter for prefixes in Search urls?

[محروم.كوم]

I'm trying to create a custom search through the url.

I've managed to get this to work:
Code:
website.com/search.php?query=mykeyword&do=process
but when I try
Code:
website.com/search.php?prefixchoice[]=mykeyword&do=process

It does not work in vb 4

Did the parameter for prefix change? and if so what is it now?
