    #   query             -   Your search string / query goes here
    #   first             -   How many do you want to get in return? (the limit)
    #   include_no_if_max -   Do you want zero results if your search yields more
    #                         results than the first X you asked for? I don't know
    #                         why you would want that.
    #   with_subdivision  -   Do you want to include organization form BEDR og AAFY
    #                         when you search?
    #   ip                -   Your client's IP. Seems to work with everything, as
    #                         long as you have xxx.xxx.xxx.xxx where x is [0-9].
