WWW::Search::AltaVistaUser(Contributed Perl DocumWWW::Search::AltaVista::NL(3)

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.
