How to install a Ajax Search with own results

Hi,

I develop in SAP_BASIS 702. My aim is to implement a search function where the user writes a part of a word equals with column of a table which is included.

I want to develop a Ajax search in Web Dynpro ABAP. I have seen the Demo in the paket swdp_demo. How can I create this search? I tested a lot of things but it is only able to search over the mapped Context and not over all defined Dates. I applied a search help for the mapped Context.

I have seen that I can write an own search help (F4 help) with a function module but this hasn't a result for the Ajax modul. Is there a possibilty develop a similar thing?

Thank's for your help.
