/**
* This methods main purpose is to support browser history.
*
* <p>When the browsers back or forward buttons are pressed, a re-search /might/ be required -
* namely if the query changes. So, as the UI requests updates of the page (show,facets, etc) this
* method checks if a search must be executed before those updates are performed.
*
* <p>It will consequently also run a search if the UI updates a search parameter without actually
* explicitly executing the search before setting of the polling.
