从索引中排除除一个之外的所有类别 - joomla 智能搜索

Question

我想让 joomla 自动重新索引某个类别（和子类别）中的所有文章，而不索引其余的。我不是在寻找 cron 工作。当我点击索引按钮时，我希望 joomla 这样做。

换句话说，不属于该特定类别或其子子类别的所有文章不应被编入索引，因此不会显示在搜索结果中。

编辑（更多信息）：这是针对我知道类别 ID 的特定网站。我可能还应该补充一点，它是一个双语网站，搜索模块在同一页面上针对每种语言出现并索引两次。 IE。它索引并显示在英语“博客”页面和德语“博客”页面上。

这可能吗，还是我需要手动删除我不想显示的索引文件？

编辑：发现工具不工作，这里是 xml 文件尝试找出原因。

编辑 来自 php 的代码，找出为什么它索引所有内容而不仅仅是类别 31。

Answer 1

哦，我认为您正在查看 xml 而不是 php。

// Check if we can use the supplied SQL query.
$query = $query instanceof JDatabaseQuery ? $query : $db->getQuery(true)
    ->select('a.id, a.title, a.alias, a.introtext AS summary, a.fulltext AS body')
    ->select('a.state, a.catid, a.created AS start_date, a.created_by')
    ->select('a.created_by_alias, a.modified, a.modified_by, a.attribs AS params')
    ->select('a.metakey, a.metadesc, a.metadata, a.language, a.access, a.version, a.ordering')
    ->select('a.publish_up AS publish_start_date, a.publish_down AS publish_end_date')
    ->select('c.title AS category, c.published AS cat_state, c.access AS cat_access');

如果要排除第 7 类添加

$query->where('a.catid <> 7');

在最后一次选择之后。

更新...或者如果您只想要类别 7 $query->where('a.catid = 7');

或者如果您只想要类别 7 及其子类别，您可以使用 IN ( comma separated list )。

更新

这就是我为生成的查询得到的结果

SELECT a.id, a.title, a.alias, a.introtext AS summary, a.fulltext AS body,a.state, a.catid, a.created AS start_date, a.created_by,a.created_by_alias, a.modified, a.modified_by, a.attribs AS params,a.metakey, a.metadesc, a.metadata, a.language, a.access, a.version, a.ordering,a.publish_up AS publish_start_date, a.publish_down AS publish_end_date,c.title AS category, c.published AS cat_state, c.access AS cat_access, CASE WHEN CHAR_LENGTH(a.alias) != 0 THEN CONCAT_WS(':', a.id, a.alias) ELSE a.id END as slug, CASE WHEN CHAR_LENGTH(c.alias) != 0 THEN CONCAT_WS(':', c.id, c.alias) ELSE c.id END as catslug,u.name AS author
FROM a1pbr_content AS a
LEFT JOIN a1pbr_categories AS c ON c.id = a.catid
LEFT JOIN a1pbr_users AS u ON u.id = a.created_by
WHERE a.catid = 31

这确实只给了我 catid 为 31 的文章。

当您编制索引时，您是使用索引按钮还是在保存时这样做？
