Question

我有一个带有134k文档的集合的Cosmos DB，每个文档包含2个字符串属性（名为ChemicalName和EchNo）和3个字符串集合（名为CasNos，IndexNos和ReachNos）。

Document JSON：

{
    "id": "9cb924ad-a100-4fce-9dc9-30ec968de585",
    "ChemicalName": "MyChemical",
    "EchaNumber": 1,
    "EcNo": "111-222-3",
    "CasNos": [
        "4444-55-6"
    ],
    "IndexNos": [
        "777-888-99-0"
    ],
    "ReachNos": [
        "01-0123456789-38-0000",
        "01-0123456789-38-0001",
        "01-0123456789-38-0002",
        "01-0123456789-38-0003",
        "01-0123456789-38-0004",
        "01-0123456789-38-0006",
        "01-0123456789-38-0007",
        "01-0123456789-38-0008",
        "01-0123456789-38-XXXX"
    ],
    "IndexScrapeDate": "2018-01-19T12:30:20.0404174Z",
    "ChemicalScrapeDate": null,
    "_rid": "96VvAOgIVwABAAAAAAAAAA==",
    "_self": "dbs/96VvAA==/colls/96VvAOgIVwA=/docs/96VvAOgIVwABAAAAAAAAAA==/",
    "_etag": "\"00007e4d-0000-0000-0000-5a69b49b0000\"",
    "_attachments": "attachments/",
    "_ts": 1516876955
}

集合具有索引定义：

  {
    "indexingMode": "consistent",
    "automatic": true,
    "includedPaths": [
      {
        "path": "/*",
        "indexes": [
          {
            "kind": "Range",
            "dataType": "Number",
            "precision": -1
          },
          {
            "kind": "Hash",
            "dataType": "String",
            "precision": 3
          }
        ]
      },
      {
        "path": "/EchaNumber/?",
        "indexes": [
          {
            "kind": "Range",
            "dataType": "Number",
            "precision": -1
          },
          {
            "kind": "Hash",
            "dataType": "String",
            "precision": 3
          }
        ]
      },
      {
        "path": "/ChemicalName/?",
        "indexes": [
          {
            "kind": "Range",
            "dataType": "String",
            "precision": -1
          },
          {
            "kind": "Range",
            "dataType": "Number",
            "precision": -1
          }
        ]
      },
      {
        "path": "/CasNos/[]/?",
        "indexes": [
          {
            "kind": "Range",
            "dataType": "String",
            "precision": -1
          },
          {
            "kind": "Range",
            "dataType": "Number",
            "precision": -1
          }
        ]
      },
      {
        "path": "/EcNo/?",
        "indexes": [
          {
            "kind": "Range",
            "dataType": "String",
            "precision": -1
          },
          {
            "kind": "Range",
            "dataType": "Number",
            "precision": -1
          }
        ]
      },
      {
        "path": "/IndexNos/[]/?",
        "indexes": [
          {
            "kind": "Range",
            "dataType": "String",
            "precision": -1
          },
          {
            "kind": "Range",
            "dataType": "Number",
            "precision": -1
          }
        ]
      },
      {
        "path": "/ReachNos/[]/?",
        "indexes": [
          {
            "kind": "Range",
            "dataType": "String",
            "precision": -1
          },
          {
            "kind": "Range",
            "dataType": "Number",
            "precision": -1
          }
        ]
      }
    ],
    "excludedPaths": []
  }

我在Dotnet Core 2.0中实现了代码，并且正在使用SQL API。

当我搜索集合时，我使用以下SQL来查找我需要的文档的ID：

SELECT VALUE c.id FROM IndexCollection c JOIN cas IN c.CasNos JOIN indx IN c.IndexNos WHERE CONTAINS(c.ChemicalName,"searchVal") OR STARTSWITH(cas,"searchVal") OR STARTSWITH(c.EcNo,"searchVal") OR STARTSWITH(indx,"searchVal")

我通过在CasNos字符串集合属性中搜索已知的部分匹配来验证它。

然后我还需要添加对ReachNos的搜索并将其添加到搜索中：

SELECT VALUE c.id FROM IndexCollection c JOIN cas IN c.CasNos JOIN indx IN c.IndexNos JOIN rch IN c.ReachNos WHERE CONTAINS(c.ChemicalName,"searchVal") OR STARTSWITH(cas,"searchVal") OR STARTSWITH(c.EcNo,"searchVal") OR STARTSWITH(indx,"searchVal") OR STARTSWITH(rch,"searchVal")

...但是一旦我添加ReachNos进行搜索，它就会停止查找任何结果，因为我使用与上面相同的搜索。如果我修改SQL只搜索ReachNos属性，它将从给定的结果中找到结果。我从该属性输入一个已知值。

任何人都可以。告诉我为什么这不起作用？我尝试了第一个SQL的所有组合，无论我搜索了什么属性，它都工作正常，直到我添加了ReachNos属性。

编辑：我应该添加我已在本地Cosmos DB Emulator和azure上测试过。 EDIT2：添加了文档JSON
