i agree with this. I'm increasingly finding that kendo is very limited in configuration options relating  to business logic. it is definitely not as "out of the box" as it is made out to be. I also keep being referenced to existing documentation by the support team and finding this documentation to be too general for it to be of any use to me. 

I agree with Manuel, too. This is a core feature, which should be available in Kendo.

I agree with Manuel. It would be a value add. JQuery Mobile does this by default, basically the list is aware of the populated data and related data source, so it filters on the text displayed automatically.

The idea of using a framework such as Kendo UI Mobile is to simplify things and minimize implementation time of these common tasks (like simple searching) such that you can spend more time on others that are more time consuming (like implementing data sources and api's).  I cannot believe that you will not implement this feature which is extremely useful for these applications just because it can be done by doing something else... if that were the response to everything, then Kendo will not be a solution for anyone.  Please reconsider this feature.
