Mod_Rewrite gives 404 Error with CodeIgniter

[eluser]Diamons[/eluser]

Code:

RewriteEngine ON
RewriteBase /
RewriteRule ^united-states/new-york/new-york-city/chelsea/10001 search?location=new-york [PT,L]

This rule gives me a 404 error from CodeIgniter. However, when I change it to this:

Code:

RewriteEngine ON
RewriteRule ^united-states/new-york/new-york-city/chelsea/10001 http://mydomain.com/search?location=new-york [PT,L]

It works fine. How can I fix the first rule to make it work?

Try:

Code:

RewriteEngine On
RewriteRule ^united-states/new-york/new-york-city/chelsea/10001 /search?location=new-york [PT,L]
