NAME
WWW::Search::HotBot - class for searching HotBot
DESCRIPTION
This class is a HotBot specialization of WWW::Search. It handles making and interpreting HotBot searches http://www.hotbot.com.
This class exports no public interface; all interaction should be done through WWW::Search objects.
SEE ALSO
To make new back-ends, see WWW::Search.
HOW DOES IT WORK?
native_setup_search
is called (from WWW::Search::setup_search
) before we do anything. It initializes our private variables (which all begin with underscore) 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 WWW::Search::http_request
to fetch the page specified by {_next_url}
. It then 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.

VERSION HISTORY
1.13
Fixed the maximum_to_retrieve off-by-one problem. Updated test cases.

HotBot does not do truncation. Therefore, if the query contains truncation characters (i.e. '*' at end of words), they are simply deleted before the query is sent to HotBot.
1.11
Fixed and revamped by Martin Thurn. Sent to John Heidemann (maintainer of WWW::Search) on 1998-02-05 for inclusion in the next release of WWW::Search.
