[phpOpenTracker-general] range problem

Hi,
I am doing the following,

$top_docs_total = phpOpenTracker::get(
  array(
    'api_call' => 'top',
    'what'     => 'document',
    'range'    => 'total',
    'limit'    => 5
  )
);

and I was under the impression that "total" meant every record ever stored on
the DB and it seems that's not the case. The reason I say this is because the
SQL query seems to be getting only the table for May (which has no data) and
it isn't including the tables from previous months. Please have a look at the
SQL and tell me if I am wrong.


CREATE TEMPORARY TABLE pot_temporary_table SELECT data_table.string AS item
FROM pot_accesslog_200505 accesslog,

pot_visitors_200505 visitors,
pot_documents data_table
WHERE visitors.client_id    = '1'
AND visitors.accesslog_id = accesslog.accesslog_id
AND data_table.data_id    = accesslog.document_id




GROUP BY visitors.accesslog_id,
data_table.string

  table:

Any help would be greatly appreciated,
