NAME
WWW::Search::LookSmart - class for searching LookSmart
SUPPORTED PLATFORMS
- Windows
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 the WWW::Search manpage objects.
SEE ALSO
To make new back-ends, see the WWW::Search manpage.
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.
TESTING
This module adheres to the WWW::Search test suite mechanism.
See $TEST_CASES below.
