Gordon,

Something like the following might do the trick for you, or at least 
provide a place to start.

(defadvice search-forward (after view-context compile disable activate)
   (if (< (count-lines (point) (window-end)) 5)
       (recenter)))

(defadvice query-replace (around view-context compile activate)
   (ad-enable-advice 'search-forward 'after 'view-context)
   (ad-activate 'search-forward)
   ad-do-it
   (ad-disable-advice 'search-forward 'after 'view-context)
   (ad-activate 'search-forward))

Good luck.
