We are on 7.11. I am curious about following: (1) Is it possible

The search box in the Record list searches in the number and text fields present in the title of each record. To add new search fields without displaying them, you can prepend something like this to the beginning of the title field in your a!listViewItem definition: left(rf!fieldName1 & rf!fieldName2 & rf!fieldName3,0).

Assuming that your record is entity-backed, an even better option is to create a view in your database that will be the source of data for your record list. Then, the CDT which connects to this view can have a text field which contains all of your search terms concatenated together, and you can use left(rf!fieldName,0) to allow users to search in your terms without displaying them.
