hasSearchFilter
jQuery Mobile provides a very easy way to filter a list with a simple client-side search feature. To make a list filterable, simply set the hasSearchFilter property to True. The framework will then append a search box above the list and add the behavior to filter out list items that don't contain the current search string as the user types.
For details of more advanced filtering options, see the jQuery Mobile documentation on List views.
