<H1><A NAME="description">DESCRIPTION</A></H1>
<P>This class is an GoTo specialization of WWW::Search.
It handles making and interpreting GoTo searches
<EM>www-GoTo.com</EM>.</P>
<P>Nothing special about GoTo: no search options. It is much like
Google in that it attempts to returm relavent search results
using simple queries.
</P>
<PRE>
This class exports no public interface; all interaction should
be done through WWW::Search objects.</PRE>
<P>
<HR>
<H1><A NAME="notes">NOTES</A></H1>
<P>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</P>

<H1><A NAME="how does it work">HOW DOES IT WORK?</A></H1>
<P><CODE>native_setup_search</CODE> 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 <CODE>{_next_url}</CODE>.</P>
<P><CODE>native_retrieve_some</CODE> is called (from <CODE>WWW::Search::retrieve_some</CODE>)
whenever more hits are needed. It calls the LWP library
to fetch the page specified by <CODE>{_next_url}</CODE>.
It parses this page, appending any search hits it finds to
<CODE>{cache}</CODE>. If it finds a ``next'' button in the text,
it sets <CODE>{_next_url}</CODE> to point to the page for the next
set of results, otherwise it sets it to undef to indicate we're done.</P>
