WWW::Search::LookSmart - class for searching LookSmart
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"; }
This class is a LookSmart specialization of WWW::Search. It handles making and interpreting LookSmart searches http://looksmart.com.
I am ignoring Looksmart's categories and just parsing reviewd sites.
LookSmart only returns 10 hits per page, less on first page since a few are categorie links.
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 (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.
This module adheres to the WWW::Search test suite mechanism.
See $TEST_CASES below.
