NAME
WWW::Search::GoTo - class for searching GoTo.com
SYNOPSIS
require WWW::Search;
$search = new WWW::Search('GoTo');DESCRIPTION
This class is an GoTo specialization of WWW::Search. It handles making and interpreting GoTo searches www-GoTo.com.
Nothing special about GoTo: no search options. It is much like Google in that it attempts to returm relavent search results using simple queries.
This class exports no public interface; all interaction should be done through WWW::Search objects.
NOTES
Uses result field $result->source which is helpful with this engine because the the URL is owner encoded. $result->source will display a plain base URL address and should be called after $result->description
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.
