NAME

       WWW::Search::AltaVista::NL - class for searching the dutch version of Alta Vista

SYNOPSIS

         require WWW::Search;
         $search = new WWW::Search('AltaVista::NL');

DESCRIPTION

       This class is an modified version of the AltaVista specialization of WWW::Search.  It handles making and
       interpreting Dutch AltaVista searches http://nl.altavista.com.

       This class exports no public interface; all interaction should be done through WWW::Search objects.

OPTIONS

       The default is for simple web queries.

       search_url=URL
               Specifies    who    to    query    with    the   AltaVista   protocol.    The   default   is   at
               "http://nl.altavista.com/cgi-bin/query";

       search_debug, search_parse_debug, search_ref Specified at WWW::Search.
       pg=aq   Do advanced queries.  (It defaults to simple queries.)

PUBLIC METHODS

       There are none defined here; see WWW::Search.

PRIVATE METHODS

   native_setup_search
       This private method does the heavy lifting after you call native_query().

   native_retrieve_some
       This private method does the heavy lifting of fetching and parsing web pages.

SEE ALSO

       To make new back-ends, see WWW::Search,

HOW DOES IT WORK?

       "native_setup_search" is called before we do anything.  It initializes our private variables  (which  all
       begin with underscores) and sets up a URL to the first results page in "{_next_url}".

       "native_retrieve_some"  is  called (from "WWW::Search::retrieve_some") whenever more hits are needed.  It
       calls the LWP library to fetch the page specified by "{_next_url}".  It parses this page,  appending  any
       search  hits  it finds to "{cache}".  If it finds a ``next'' button in the text, it sets "{_next_url}" to
       point to the page for the next set of results, otherwise it sets it to undef to indicate we're done.

AUTHOR and CURRENT VERSION

       "WWW::Search::AltaVista::NL" is written and maintained by Erik Smit, <zoiah@zoiah.nl>.

       The best place to obtain "WWW::Search::AltaVista::NL" is from  Martin  Thurn's  WWW::Search  releases  on
       CPAN.   Because AltaVista sometimes changes its format in between his releases, sometimes more up-to-date
       versions can be found at http://www.zoiah.nl/programming/AltaVistaNL/index.html.
