WHAT IS WWW::Search?
--------------------

WWW::Search is a collection of Perl modules which provide an API to
WWW search engines.  Currently WWW::Search includes back-ends for
variations of AltaVista, Dejanews, Excite, HotBot, Infoseek, Lycos,
Magellan, PLweb, SFgate, Verity, WebCrawler, and Yahoo.  We include
two applications built from this library: AutoSearch (an program to
automate tracking of search results over time), and WebSearch, a small
demonstration program to drive the library.  Back-ends for other
search engines and more sophisticated clients are currently under
development.

Because WWW::Search depends on parsing the HTML output of web search
engines it will fail of the search engine operators change their
format (an unfortunately frequent occurrence).  WWW::Search includes a
test suite for most back-ends which verifies that it's functioning
correctly.  As of the day of the release the current back-end
status is:

AltaVista		working
Dejanews		working
Excite			working
ExciteForWebServers	working
FolioViews		working
Gopher			not working? (not in test suite)
HotBot			working
Infoseek		working
Livelink		not working? (not in test suite)
Lycos			working
Magellan		not working (maybe gone?)
MSIndexServer		working
Null			working
PLweb			working
Search97		working
SFgate			working
Simple			not working? (not in test suite)
Verity			not working (not in test suite)
WebCrawler		working?
Yahoo			working

Yahoo's test suites are sometimes flakey.

(others are currently under development, see contributors below for details)

WHAT IS AutoSearch?
-------------------

WWW::Search's primary client is AutoSearch.  AutoSearch performs a
web-based search and puts the results set in a web page.  It
periodically updates this web page, indicating how the search changes
over time.  Sample output from WWW::Search can be found at
<http://www.isi.edu/lsam/tools/autosearch/>.  Output format is configurable.

See the man page for AutoSearch details, or Demonstration section
below for the quick-start instructions.

REQUIREMENTS
------------

WWW::Search requires Perl5 and libwww-perl.
For information on Perl5, see <http://www.perl.com>.
For libwww-perl, see <http://www.sn.no/libwww-perl/>.
Both are also available from the Comprehensive Perl Archive
Network (CPAN). Visit <http://www.perl.com/CPAN/> to find a CPAN
site near you.

At this time WWW::Search is tested under Perl version 5.004_04.

AVAILABILITY
------------

The latest version of WWW::Search should always be available from
<http://www.isi.edu/lsam/tools/WWW_SEARCH/>.  Alpha releases are only
available here (not at CPAN).

WWW::Search is also available as part of CPAN.  Visit
<http://www.perl.com/CPAN/> to find a CPAN site near you.

Feedback about WWW::Search is encouraged.  If you're using it for a
neat application, please let us know.  If you'd like to (or have)
implemented a new back-end for WWW::Search, let us know so we don't
duplicate work.
