This method is deprecated.
Deprecated in Stash 2.0 for removal in 3.0. When a caller provides a filter for a search, it is
expected that the caller will retain knowledge of that filter in order to apply it to subsequent
pages as they are requested. Additionally, because many types support filtering which is more
complex than can be applied by a single
String, the support for including the filter with
the page offered by this parameter is frequently insufficient. Existing code which populates this
property will continue to do so, but has been deprecated for removal. Such methods will document
the expected behaviour moving forward.
