Hi,  
I have an index which has nested list object. I need to only update certain values based on a condition. List of history with dates and values I need to update only values matching with dates.  
In the below example  
**I only want to update historydate 2020-02-01 value not other historydates values in history in NEST C# Client.**  
I couldn't find NEST documentation anywhere. Could someone please help me.  
**Example data**

```auto

[
  {
    "id": 1,
    "description": "market 1",
    "salesprice": 10.9,
    "cost": 7.95957,
    "history": [
      {
        "historydate": "2020-01-01",
        "quantity": 1
      },
      {
        "historydate": "2020-02-01",
        "quantity": 2
      }
    ]
  },
  {
    "id": 2,
    "description": "market 2",
    "salesprice": 12,
    "cost": 12,
    "history": [
      {
        "historydate": "2020-01-01",
        "quantity": 1
      },
      {
        "historydate": "2020-02-01",
        "quantity": 2
      }
    ]
  },
  {
    "id": 3,
    "description": "market3",
    "salesprice": 15,
    "cost": 15,
    "history": [
      {
        "historydate": "2020-01-01",
        "quantity": 10
      },
      {
        "historydate": "2020-02-01",
        "quantity": 20
      },
      {
        "historydate": "2020-03-01",
        "quantity": 30
      }
    ]
  }
]  
  

```

Thank you
