使用sphinx search v2.2.9，此查询返回特定记录：
((@(author) fstaed) | (@(authsurname) fstaed) | (@(authori) fstaed) )
此查询也会返回相同的记录：
(@(issued) 2007)
但是这个查询（我认为这是上述两个查询的隐含“AND”组合不会返回记录：
(@(issued) 2007) ((@(author) fstaed) | (@(authsurname) fstaed) | (@(authori) fstaed) )
为什么？
更新1：
我可以使用mysql命令行重现此问题，下面显示了运行上述3个测试中的每一个。请注意，id：187在两个单独的结果集中，但不在组合结果集中。

更新2：
我还应该提到“work”索引是包含“iresrevi1_core”和“iresrevi2_core”的多个索引之间的分布式索引。 iresrevi2_core索引中的“已发布”字段为空（iresrevi1_core索引中不为null），并且正在搜索的authori字段在相反索引iresrevi1_core中为空（在iresrevi2_core索引中不为null）。
我认为这可能与此有关？我可以确认，如果我直接查询2个索引，iresrevi1_core索引将返回已发布的搜索数据，但iresrevi2_core索引将不返回已发布的搜索数据。反之亦然，iresrevi2_core将返回作者搜索数据，但iresrevi1_core将不会。
我分发了多个索引，以便我可以使用“非中缀”方法索引我想要搜索的所有字段（强制“中缀”字段在此索引中为空）以及我想要的所有字段使用“中缀”方法的搜索位于另一个索引上，所有“非中缀”字段都被清空。 2个源/索引看起来像这样：

答案 0 :(得分：1)
所以是的，它是问题的多个不同的索引。 UNION没有加入。
除了你找到的主题之外，这里还有一个更新的主题，提到可能使用@@ relax来解决它。它可能会为分布式索引工作。
