=head1 NAME
Bio::DB::EUtilities::egquery - counts for a global query of Entrez databases
=head1 SYNOPSIS
    my $egquery = Bio::DB::EUtilities->new(
                                     -eutil    => 'egquery',
                                     -term     => 'dihydroorotase'
                                      );
    print $egquery->get_response->content;
=head1 DESCRIPTION
L<EGQuery|Bio::DB::EUtilities::egquery> provides Entrez database counts
in XML for a single search using NCBI's Global Query.  No further parsing of
the XML data is processed at this time.
=head2 NCBI EGQuery Parameters
The following are a general list of parameters that can be used to take
advantage of EGQuery.  Up-to-date help for EGQuery is available at this URL
(the information below is a summary of the options found there):
  http://eutils.ncbi.nlm.nih.gov/entrez/query/static/egquery_help.html
=over 3
=item C<term>
Search term or phrase with or without Boolean operators.  This can use search
field descriptions and tags (Note: these may be database specific and are
better used with L<ESearch|Bio::DB::EUtilities::esearch>.
