Plug-in for Smart Search on Joomla: no results - search

Question

I'm writing a plug-in for my component. For this component I have table "#__radiocatalog_item" with columns id, name, description, and I need to lookup at column name. For this, I wrote this plugin:
<?php
defined('JPATH_BASE') or die;
require_once JPATH_ADMINISTRATOR.'/components/com_finder/helpers/indexer/adapter.php';
class PlgFinderRadioitem extends FinderIndexerAdapter
{
protected $context = 'Radioitem';
protected $extension = 'com_radiocatalog';
protected $layout = 'item';
protected $type_title = 'item';
protected $table = '#__radiocatalog_item';
protected $state_field = 'parent';
protected $autoloadLanguage = true;
protected function setup()
{
return true;
}
public function onFinderDelete($context, $table)
{
if ($context == 'com_radiocatalog.item')
{
$id = $table->id;
}
elseif ($context == 'com_finder.index')
{
$id = $table->id;
}
else
{
return true;
}
return $this->remove($id);
}
public function onFinderChangeState($context, $pks, $value)
{
if ($context == 'com_radiocatalog.item')
{
$this->itemStateChange($pks, $value);
}
if ($context == 'com_plugins.plugin' && $value === 0)
{
$this->pluginDisable($pks);
}
}
protected function index(FinderIndexerResult $item, $format = 'html')
{
if (JComponentHelper::isEnabled($this->extension) == false)
{
return;
}
$item->url = $this->getURL($item->id, 'com_radiocatalog&layout=item', $this->layout);
$item->route = 'index.php?option=com_radiocatalog&view=item&layout=item&id='.$item->id;
$item->addTaxonomy('Type', 'Radioitems');
$item->addTaxonomy('Language', $item->language);
$this->indexer->index($item);
}
protected function getListQuery($sql = null)
{
$db = JFactory::getDbo();
$sql = $sql instanceof JDatabaseQuery ? $sql : $db->getQuery(true);
$sql->select('a.id as id, a.name as title, a.description as description');
$sql->from('#__radiocatalog_item AS a');
return $sql;
}
protected function getStateQuery()
{
$sql = $this->db->getQuery(true);
$sql->select($this->db->quoteName('a.id'));
$sql->select($this->db->quoteName('a.name').' as title');
$sql->from($this->db->quoteName('#__radiocatalog_item') . ' AS a');
return $sql;
}
}
?>
After full indexing, search on the site does not work.

I was struggling with the same problem. So I enabled Joomla debugging {Global Configuration / System / Debug System = true} and tried to search for a term "myterm" using public site SmartSearch module. Then I checked the performed SQL queries. First, the term was found:
SELECT t.term, t.term_id
FROM j_finder_terms AS t
WHERE t.term = 'myterm'
AND t.phrase = 0
with ID=653 (used later):
SELECT l.link_id,m.weight AS ordering
FROM `j_finder_links` AS l
INNER JOIN `j_finder_links_terms2` AS m
ON m.link_id = l.link_id
WHERE l.access IN (1,1)
AND l.state = 1
AND (l.publish_start_date = '0000-00-00 00:00:00' OR l.publish_end_date <= '2014-01-04 17:34:00')
AND (l.publish_end_date = '0000-00-00 00:00:00' OR l.publish_end_date >= '2014-01-04 17:34:00')
AND m.term_id IN (653)
But this query didn't return any result, because j_finder_links.access and j_finder_links.state values were set to 0 instead of 1.
So my suggest you to check the queries and if you have the same problem, try to change your query from getStateQuery() method or select "1 AS access, 1 AS state" in the getListQuery() query and leave the $state_field variable unset.
I'm sorry for a vague explanation, I don't know much about how the SmartSearch work, I'm just trying to make it work somehow with my component.
