A, and probably the biggest, internet search engine, reachable e.g. at http://google.com

See [Fuzzy Google truth] for an oracle that filters out how many pages Google found for a query.

For examples of use of the "Google Web API" with Tcl, see
[http://cedar.intel.com/cgi-bin/ids.dll/content/content.jsp?cntKey=Generic+Editorial%3a%3aws_google&cntType=IDS_EDITORIAL&catCode=CJA].
Active discussion of the API is available
through google.* netnews
[http://groups.google.com/groups?group=google.public.web-apis].

[[Anyone want to add info here about code to search google's comp.lang.tcl* newsgroups?]]

[CL] daily uses something like
    set keywords "DDE+Word"
    set URL http://www.deja.com/\[ST_rn=ps]/qs.xp?ST=PS&svcclass=dnyr&firstsearch=yes&preserve=1&QRY=$keywords&defaultOp=AND&DBS=1&OP=dnquery.xp&LNG=english&subjects=&groups=comp.lang.tcl&authors=&fromdate=&todate=&showsort=score&maxhits=25

[[Anyone want to add info here about code to convert usenet message-id strings into google URLs?]]

Use http://groups.google.com/groups?as_umsgid=$message_id (replacing $message_id with the usenet message-id of the post in question).

If you check http://www.google.com/apis/api_faq.html , you will see that
there is a [WSDL] definition for google, allowing an application using
[SOAP] to access the host.  A Tcl example doing this would be wonderful -
it could eliminate at least some cases of [web scraping].
