disable codeigniter uri security

[eluser]kakawett[/eluser]
Hi.

My site has king of search engine and people can type what ever they want.
The problem is that the character "+" isn't allowed and I want to have beauty url : search/My+Keywords+Whatever
i've setup the search/(.*) in routes.php, but the documentation says that all character are prohibited except A-Za-z0-9 and a few others.

So how do I enable the '+' ?
Thanks.

Oh and the search has to support different languages so it must support characters like 세, ü, é, etc...

You'd probably be better off passing the search string through post if you want all those options.

No - need google to be able to index some search results... srsly, how do I disable that ? how do people from korean do ?

In the config file turn on query strings and set the allowed uri characters.

Perhaps this could be helpful?

Simple Search: passing form variable to URI?

@Ben Edmunds : Yeah but if I turn on the query string... it will do it for ALL my controllers right ? so I wont have any pretty url at all, only index.php?c=xxx&m=xxxx&yyyY=aaaa.... or is it possible to enable it only for the search ?

And I don't want any .php, I really want to have the /searc/any+keyword+any+language structure.

@barhainph yeah it looks working but the url will be escaped so I won't have pretty urls that I need.

Do you guys have an idea ? maybe the Ben ones is the solution, but isn't there any other way to do it ?
