WWW::Search::AltaVista::NL - class for searching the dutch version of Alta Vista
require WWW::Search; $search = new WWW::Search('AltaVista::NL');
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.
The default is for simple web queries.
Specifies who to query with the AltaVista protocol. The default is at http://nl.altavista.com/cgi-bin/query;
http://nl.altavista.com/cgi-bin/query
Do advanced queries. (It defaults to simple queries.)
To make new back-ends, see WWW::Search,
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_setup_search
{_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.

WWW::Search::AltaVista::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.
