# Bio::DB::EUtilities::egquery(3pm)

Bio::DB::EUtilities::egquery - counts for a global query of Entrez databases

```
    my $egquery = Bio::DB::EUtilities->new(
                                     -eutil    => 'egquery',
                                     -term     => 'dihydroorotase'
                                      );
```

```
    print $egquery->get_response->content;
```

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.\
