WWW::Search::Metapedia - class for searching online Encyclopedias

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

Silly class I made to sponge off a Encyclopedia meta search engine. Searches multi online Encyclopedias.

Covers:

Encylopedia Britannica - paid subscription service Encarta Knowledge Adventure Infoplease

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

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_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.
