Remember our search results settings within and across sessions
At present, any time a new search is started - whether by entering a search term or clicking a facet on the left - the search results revert to default settings: 15 items per page and the applicable default sort (typically relevance). This happens even after I've explicitly changed to 60 items per page and, for example, sorting by title.
This is a solved problem in modern web sites. Please preserve such explicitly chosen search results settings.
