How to create a search text box on Web Intelligence Rich Client Tool?

Hi all,

My task is research to build a search text box by a Entry Input Control, which can let a user typing in a word/phrase, then the control will list down some matched results for user to select.  It’s like a Matched Cases search.

I can’t find any way to do it with Entry Input Control and I don’t want a user have to click button Refresh every time he needs to search with another texts using query prompts.

Would anyone please tell me how I can create that search text box?
