I am not sure exactly what previous code you are refering to, but
I don't think it matters.

One way of doing this is to write your own store. This might sound
scarier than it really is. For example write a class called:
search-key-and-results
which implements the store interface.
Almost all methods of the store interface can be no-ops.
The only two that are really important for displaying are:
(defmethod find-persistent-objects ((store hash-store) class-name
&key order-by range &allow-other-keys)
(defmethod count-persistent-objects ((store hash-store) class-name &key
&allow-other-keys)
(hash-table-count (data store)))
Also add to the search-key-and-results class an ivar 'search-string'.
If build your class search-key-and-results in such a way, you can
do roughly the following:
...
(let ((search-and-results (make-instance 'search-key-and-result)))
...
(make-instance 'quickform :data search-and-results .....)
(make-instance 'datalist :class-store search-and-results))
....
Now your datalist can access your search results using the store
interface.
The quickform will render your search box, using the normal mechanisms,
so you can modify the 'search-string' slot.
One thing that will not work out of the box is that you have to call
mark-dirty on your datalist widget after the content of your
search results is changed.
