Most of these solutions will only work if you only have a single function called index() in your controller. If you have this in your routes:

$route['search/(:any)'] = 'search/index/$1';

With the above in your routes, what will happen is that your search function will work but then if you add any other functions to that same controller they'll all be redirected to /search/index/$1.

The only solution I can think of that allows you to use the URL you want while still being able to add any other functions to your search controller is to add a sort of messy conditional to your routes file. Here's what it will look like and what it does:

$request = $_SERVER['REQUEST_URI']; // Only add this for readability if(!strpos($request, 'search/another_function') || !strpos($request, 'search/more_functions')) { $route['search/(:any)'] = 'search/index/$1'; }

What this is doing is basically saying "if the requested URL doesn't contain the name of any of my search controller functions then it must be meant for the index so we'll activate the route rule for index".

This will allow you to take requests for search/any_other_functions_you_have without issue and only activate the rule for hiding the index function when a request URI doesn't match any of them.

One side effect of this is that you'll never get a 404. For example, if someone enters a URL like "yourdomain.com/search/something" and they expect it to show a non-search result page they won't get a 404 alerting them to the fact that there is no page like that and instead the app will assume what they typed is a search term. However, it sounds like this isn't much of an issue for you and I don't see it being such a terrible thing for one controller to be unabe to return 404s.
