NAME ^

WWW::Search::Snap - class for searching Snap.com!

SYNOPSIS ^

    require WWW::Search;
    $search = new WWW::Search('Snap');

DESCRIPTION ^

Class specialization of WWW::Search for searching http://snap.com. Snap.com can return up to 1000 hits.

This class exports no public interface; all interaction should be done through WWW::Search objects.

OPTIONS ^

Some options for modifying a search

{'KM' => 'a'} All the words
{'KM' => 'b'} Boolean Search
{'KM' => 'o'} Any of the words
{'KM' => 't'} Searches Title only
{'KM' => 's'} All forms of the words

SEE ALSO ^

To make new back-ends, see WWW::Search, or the specialized AltaVista searches described in options.

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.
