Search without login


Hi guys,

In our application (a mindmap application, you can get it from here:, people can set a search term then application will search twitter with the search term and display result on screen.
It was quite easy in Api 1.0, we just needed to call GET then everything were there.
I tried to replace the url with the url from API 1.1 and got 400 error.
Is there still a simple easy way to do what I want? Or I have to implement OAuth things in my App? I just need to search twitter with the keyword, it’s nothing to do with the user information.

Thank you very much.
