Cosmos Mongo API “In” Array expression issue

问题

Are there issues with the IN expression? We are having issues where it doesn't find the results we are asking for even though it exists?

{ "SerialNumber": "V8073023", "_t": "DeviceEventDataEvent", "EventType": NumberInt(4), "isDeleted": { $in: [false,null] }, "EventNumber": 122 } Returns the document correctly, however when using IN

{ "SerialNumber": "V8073023", "_t": "DeviceEventDataEvent", "EventType": NumberInt(4), "isDeleted": { $in: [false,null] }, "EventNumber": { $in: [122] } } No data is returned.

I tried to reproduce your issue on my side but failed. Please refer to my details.

My sample documents in my cosmos db:

{
        "id" : "1",
        "CustomerId" : 1,
        "Orders" : [
            "a",
            "b",
            "c"
        ]
},
{
        "id" : "2",
        "CustomerId" : 2,
        "Orders" : [
            "e",
            "f",
            "g"
        ]
}

My db was built in the region East Asia.If you have any difference with me, you could edit it.

Microsoft got back to me, issue their side. Thanks to everyone involved for still assisting.

Thank you David for reporting this! I investigated the issue, it’s a bug on our side manifesting under a combination of conditions. I already have made a fix for it and will check it in by end of week (then it’s up to our deployment cycle to propagate the fix to all datacenters around the world). Let me know if you have queries that don’t work and are blocking you. Best regards, Orestis
