Question

我有一个Sphinx 3.1.1.安装，我想在其中显示使用DocStore找到的结果的摘要。但是，该代码段只是返回文档内容的开头。

我使用的查询：

SELECT id, SNIPPET(content, QUERY()) AS snippet FROM test_index WHERE MATCH('test');

这将给我返回如下结果：

+--+--------------------------------------------------------+
|id |snippet                                                |                
+-----------------------------------------------------------+
|1  |this is a test document to test Sphinx 3.1.1 ...       |
+-----------------------------------------------------------+
|2  |another test document to test Sphinx 3.1.1. ...        |
+--+--------------------------------------------------------+

请注意，返回的代码段在搜索词b周围没有突出显示的test标签，并且返回的代码段是文档的起始字符串。例如，如果我搜索test2，结果是相同的（文档中的内容进一步包含test2，但是该片段仅显示内容中的前x个单词，而没有突出显示？）

我的索引的配置是：

index test_index
{
    type          = rt
    path          = /mtn/data001/test_index
    rt_field      = content
    stored_fields = content
}

我做错了什么，为什么我的代码片段不包含突出显示标签？

嗯，我只是尝试将test_index复制/粘贴到配置文件，然后启动sphinx3实例...

因此，似乎3.1.1确实可以正常工作，但是您的配置有些奇怪。

也许尝试删除test_index文件（当searchd关闭时），然后重试。也许您已经以某种方式破坏了索引文件（例如，自创建以来更改了配置）-在实验过程中这样做很容易

Sphinx 3.1.1未返回正确的代码段
