Add a Reset/Clear button to the Errata Search page ?

[jypeter]

I'm experimenting a bit with the Errata Search, and when you are trying multiple facets combinations, it could be nice to have a button to clear the current query (like the Reset button on the ESGF search page )

The workaround I have found for now is to just reload the page (with F5), because the query does not appear in the URL. Don't know if this kind of trick should appear in the FAQ
