# RFC 1738 says:
#
#   A WAIS URL takes one of the following forms:
#
#     wais://<host>:<port>/<database>
#     wais://<host>:<port>/<database>?<search>
#     wais://<host>:<port>/<database>/<wtype>/<wpath>
#
#   where <host> and <port> are as described in Section 3.1. If :<port>
#   is omitted, the port defaults to 210.  The first form designates a
#   WAIS database that is available for searching. The second form
#   designates a particular search.  <database> is the name of the WAIS
#   database being queried.
