    processing done on the home page. Any queries sent to the homepage are
    redirected to /around.

    If nothing matched error shown. If multiple match show alternatives.

    LIST: If a search could be resolved to a lat/lon, or a lot/lon was in query
    show matches near that location.

    match is found redirect to '/report/new' for the partial to be completed.

    stored. If no location can be deteremined redirects back to '/around'. All
