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

               "http://nl.altavista.com/cgi-bin/query";

       pg=aq   Do advanced queries.  (It defaults to simple queries.)

PRIVATE METHODS

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.
