Overload ASP.NET MVC Actions

How can I overload actions in ASP.NET MVC, but with support for GET QueryString? I tried to do something like this:

public JsonResult Find(string q)
{
    ...
}

public JsonResult Find(string q, bool isBlaBla)
{
    ...
}

But whenever I access /controller/find?q=abc or /controller/find?q=abc&isBlaBla=false it throws anSystem.Reflection.AmbiguousMatchException.

How to fix this?

ASP.NET doesn't support action overloading with the same HTTP verb.

You actually don't need to create overloads. All you need to do is create a single action method with all the possible arguments that you expect and it will map the values (where possible) for you. 

public JsonResult Find(string q, bool isBlaBla)
{

}

You could even make use of Optional Parameters and Name Arguments if you're using C# 4.0

you should be using routes e.g. find/abc or find/abc/false

if you must use a query string u can use no arguments and access the querystring in the HttpContext
