Hi everybody, Looking for some information on ez search engine, I've studied the mecanism of the ez engine and I did'nt understand what is doing this query in the seach function of the eZSearchEngine :
if ( $searchPartsArray == null )
{
$db->createTempTable( "CREATE TEMPORARY TABLE ezsearch_tmp_0 ( contentobject_id int primary key not null, published int )" );
$db->query( "INSERT INTO ezsearch_tmp_0 SELECT DISTINCT ezsearch_object_word_link.contentobject_id, ezsearch_object_word_link.published
FROM ezcontentobject,
ezsearch_object_word_link
$subTreeTable,
ezcontentclass,
ezcontentobject_tree
WHERE
$searchDateQuery
$sectionQuery
$classQuery
$classAttributeQuery
$subTreeSQL
ezcontentobject.id=ezsearch_object_word_link.contentobject_id and
ezcontentobject.contentclass_id = ezcontentclass.id and
ezcontentclass.version = '0' and
ezcontentobject.id = ezcontentobject_tree.contentobject_id and
ezcontentobject_tree.node_id = ezcontentobject_tree.main_node_id
$sqlPermissionCheckingString" );
$this->TempTablesCount = 1;
$i = $this->TempTablesCount;
}
This means that this query is executed meanwhile there are no wordlinks in the ezsearch_object_word_link table. So, index are not used and mysql browses the whole table... I think it is related to this bug. http://ez.no/community/bugs/query_very_slow_in_ezsearch Does anybody have an answer ?
