在我的结果集中查询最佳结果的同时，我还使用Sphinx生成了一个代码段。为此，我使用以下SELECT语句：
SELECT id, SNIPPET(Content, '(55byddQ%)') AS Snippet FROM RTTest WHERE MATCH(' (55byddQ%)');
但是，此查询返回了一些错误的结果（例如ID 1）：
+------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

正如您在ID 1的代码段中所见，它还在突出显示诸如0yMqTJfByLxZRwNu9zYXv0m1miVLwus_fxl0<b>ZxNkrfpN</b>GNsG8KeEzr1fn05yTa7fJkq9ZHSjHLB2之类的匹配项，而我正在搜索55byddQ%。
因此，摘要功能无法向我返回正确的结果，但我不知道为什么不这样做。
