  ¦  If the processing of a form is idempotent (i.e. it has no lasting
  ¦  observable effect on the state of the world), then the form method
  ¦  should be `GET'. Many database searches have no visible
  ¦  side-effects and make ideal applications of query forms.

  ¦  The "get" method should be used when the form is idempotent (i.e.,
  ¦  causes no side-effects). Many database searches have no visible
  ¦  side-effects and make ideal applications for the "get" method.

In the example posted, the form is idempotent.
