sphinx 搜索：使用隐式查询且不返回结果
sphinx search: querying using implicit AND not returning the result
使用 sphinx 搜索 v2.2.9，此查询 return 是一条特定记录：
((@(author) fstaed) | (@(authsurname) fstaed) | (@(authori) fstaed) )
此查询还 return 相同的记录：
(@(issued) 2007)
但是这个查询（我认为是上述两个查询的隐含 "AND" 组合不 return 记录：
(@(issued) 2007) ((@(author) fstaed) | (@(authsurname) fstaed) | (@(authori) fstaed) )
为什么？

我可以使用 mysql 命令行重现此问题，下面显示了 运行 以上 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。

更新二：
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。 "issued"字段在iresrevi2_core索引中为null（在iresrevi1_core索引中不为null）并且正在搜索的authori字段在对面索引iresrevi1_core中为null（在iresrevi1_core中不为null iresrevi2_core 索引）。
我想这可能与此有关？我可以确认，如果我直接查询 2 个索引，iresrevi1_core 索引将 return 发布的搜索数据，但 iresrevi2_core 索引不会 return 发布的搜索数据。反之亦然，iresrevi2_core 将 return 作者搜索数据，但 iresrevi1_core 不会。
我有多个分布式索引，这样我就可以使用 "non infix" 方法索引我想搜索的所有字段（强制 "infix" 字段在此索引中为空）和所有我想使用 "infix" 方法搜索的字段位于另一个索引上，所有 "non-infix" 字段都被清空了。 2 sources/indexes 看起来像这样：
source srcresrevi1 : srcresrev

sql_query = \
select SQL_NO_CACHE `work`.`ID` AS `ID`, '' as authori \
from work \
WHERE (`work`.`ID` BETWEEN $start AND $end) \

sql_joined_field = authsurname from ranged-query; \

所以是的，问题在于多个不同的索引。联合不加入。
除了您找到的线程外，这里还有一个更新的线程，其中提到可能使用@@relaxed 来解决它。它可能仍然适用于分布式索引。
