这个couchbase索引有什么问题？

Question

我创建了这个couchbase索引

CREATE INDEX `idx_additionalOrderCode` ON 
`order`(ALL ARRAY s.`value` FOR s IN additionalOrderCode WHEN s.`typeCode`= "MYCODE" END)
WHERE _class = "com.entrprise.OrderEntity" 

基于此页面中的示例

https://docs.couchbase.com/server/6.0/n1ql/n1ql-language-reference/indexing-arrays.html

但是当我用这个选择查询查询这个索引时：

SELECT * FROM `order` 
WHERE `_class` = "com.entrprise.OrderEntity" 
AND ANY s IN additionalOrderCode SATISFIES ( s.`value` = "130047777" ) and (s.typeCode = "MYCODE" ) END

我收到了错误

 "msg": "No index available on keyspace order that matches your query. Use CREATE INDEX or CREATE PRIMARY INDEX to create an index, or check that your expected index is online."

没有主索引支持查询，我希望我的所有查询都由二级索引支持。

我使用的是Enterprise Edition 6.0.0 build 1693

谢谢你的帮助

用这个索引解决了它（我只删除了distinct和array之间的ALL）

CREATE INDEX `idx_additionalOrderCode` ON `order`
 (distinct (array (aoc.`value`) for `aoc` in `additionalOrderCode` WHEN aoc.`typeCode`= "WLEC"  END), orderTypeCode)
 WHERE (`_class` = "com.entreprise.OrderEntity")
