How to allow for null parameters in API Attribute Routing? [duplicate]

Question

I have a method which conducts a search based on 3 criteria:

Author
Title
Keywords

The API method I have created for this search currently looks like this:

[Route("A={author};T={title};K={keywords}")]
[ResponseType(typeof(bool))]
public HttpResponseMessage Get(string author, string title, string keywords)
{            
    //Code for search
}

The method works perfectly fine when all 3 parameters are passed. However, if I were to simply just enter an author and not title or keywords, I receive a Not Found error.

Is there a way I can modify the route to allow for when 1 or more parameters are null/empty strings?

Any parameters not mentioned in the Route string will be mapped when sent as part of the query string of the URL. For example:

http://www.yourapi.com/path/to/endpoint?author=DouglasAdams&keywords=Hitchhiker

will call your method with author = "DouglasAdams", title = null, and keywords = "Hitchhiker" if you use Route("path/to/endpoint").
