// tuple (artifact_ids, matching_ids) -- where ids are
// comma separated --, we will have to do the join in php
// by concatenating strings.
// Example:
// $artifact_ids = $changeset_ids = '';
// foreach ($trackers as $tracker) {
// merge($artifact_ids, $changeset_ids, report->getMatchingIdsInDb(..., $tracker, ...));

// crosssearch->retrieveColumns($artifact_ids, $changeset_ids)

// And if we are feeling lucky, we can also move the
// reportdao->searchMatchingIds in searchdao since it make more sense.

// Possible caveat:
