I had to create something like that, i had a search field and a block used for the results. here's what i've done:
-create an item to store the old value of the search field.
-create when-new-item-instance in the search field, which creates a timer.
-create when-timer-expired, compare the value of the search field with the old and then save the new value. If the values are diferent set the default_where of the block and execute the query, if the value is the same, don't do anything so no unnecessary querys are made. Also remember to delete the timer if system.current_item is not the search field.
This should create an effect like the lov, depending on the timer time and the number of records returned... I know this is not very good in performance, but it will do the job.
hope it helps.
