我想要一个查询（和索引）来检索基于propertyCodes.provider.code.value.value和propertyCodes.provider.providerCode的文档。我已设法单独执行每项操作，但我不确定如何在单个查询中合并它们。

SELECT meta().id FROM giata_properties AS gp USE INDEX(`#primary`) WHERE ANY v WITHIN gp.propertyCodes.provider[*].code SATISFIES v.`value` = '150613' END;

SELECT meta().id FROM giata_properties AS gp USE INDEX(`#primary`) WHERE ANY v within gp.propertyCodes.provider[*].providerCode SATISFIES v = 'hotelbeds' END;

例如，我想获取包含propertyCodes.provider.code.value.value 304387 provider且hotelbeds也是overflow: hidden;的文档，因为代码值可以在文档上重复，但是code和providerCode组合是唯一的。

以下是查询和索引。

查询。

SELECT META().id
FROM giata_properties AS gp
WHERE ANY p IN propertyCodes.provider SATISFIES ( ANY v WITHIN p.code SATISFIES v.`value` = '304387' END ) AND p.providerCode = 'hotelbeds' END;

索引。

CREATE INDEX idx_value ON giata_properties
( DISTINCT ARRAY ( DISTINCT ARRAY v.`value` FOR v WITHIN p.code END ) FOR p IN propertyCodes.provider END );

CREATE INDEX idx_providerCode ON giata_properties
( DISTINCT ARRAY p.providerCode FOR p IN propertyCodes.provider END );

Couchbase N1QL数组查询
