fulltext query in joomla

问题

How do I buld a fulltext search query with joomla objects. I have been trying but it's not working

   $db = JFactory::getDBO();
        $query = $db->getQuery(true);
        $query->select('*');
        $query->from('#__unis_subjects AS s');
        $query->join('', '#__unis AS u ON s.university = u.id');
        $query->join('', '#__unis_faculties AS f ON f.id = s.faculty');
        $query->where('MATCH (s.subject) AGAINST ("' . $query . '")');

        if (!$db->query()) {
            throw new Exception($db->getErrorMsg());
        }

        $data = $db->loadObjectList();

        var_dump($query);

the result outputs template config parameters

回答1:

Your table must be set up using ENGINE = MyISAM (not InnoDB) and the columns you're searching must be set to FULLTEXT indexing.

You can easily set your table to MyISAM in phpMyAdmin via the 'SQL' tab...

ALTER TABLE `tablename` ENGINE=MYISAM;

In Joomla 2.5+ (likely 3+ as well) in my query as a where clause I used...

->where('MATCH ('.$db->quoteName('columnname').') AGAINST ('.$db->quote($words_or_phrase_to_search_for).')');

Further testing is in order but so far it seems to be working as expected.

The $query inside the where condition seems strange to me.
