DESCRIPTION
   PubMed is the National Library of Medicine's search service that
   provides access to over 11 million citations in MEDLINE, PreMEDLINE, and
   other related databases, with links to participating online journals.
   This module is an interface to access this service via the generic
   "WWW::Search" interface. This class exports no public interface; all
   interaction should be done through WWW::Search objects.

     $www_search->maximum_to_retrieve( 10 );

     $www_search->native_query( my $query_pubmed = 'stress AND cardiovascular risk' );

     while ( my $r = $www_search->next_result )
     {
        print "$_\n" for ( $r->url, $r->title, $r->description );
     }

NCBI DISCLAIMER AND COPYRIGHT
   I personally encourage everybody to read
   <http://www.ncbi.nlm.nih.gov/About/disclaimer.html> before using the
   service via this module. Because using it is like surfing the original pages
   i am sure all legal consequences that refer to the website are
   inherited by this tool.

   Please read http://www.ncbi.nlm.nih.gov/About/disclaimer.html.

BUGS AND CAVEATS
   While this tool tries to present the original information in its essence
   via extracting interesting information, it may fail to do so. So do not
   rely on the information retreived by this tool without rigorous
   confirmation of the original sources (http://www.pubmed.com website or
   original print journal articles).

   Because the parser depends on the static webserver response it may brake
   as soon as the html is significantly altered. Please inform the author
   via

   http://rt.cpan.org

   if this happens and subject all other reports there. Escpecially I am open
   to every improvement towards robust parsing.
