NAME
WWW::Search::LookSmart - class for searching LookSmart
SYNOPSIS
use WWW::Search; my $Search = new WWW::Search('LookSmart'); # cAsE matters my $Query = WWW::Search::escape_query("Where is Jimbo"); $Search->native_query($Query); while (my $Result = $Search->next_result()) { print $Result->url, "\n"; }
DESCRIPTION
This class is a LookSmart specialization of WWW::Search. It handles making and interpreting LookSmart searches http://looksmart.com.
LookSmart will first display it's own internal site results from it's many categories if found there, else it will return outside results from the web. Thus, depending on the query there will be slightly two different formats returned depending on whether or not LookSmart finds them in it's own internal categories. All in all, this is a nice search engine!
LookSmart only returns 10 hits per page and there is no search options.
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.
