    Description

      Hi,

      I would like to perform a vector cosine similarity in mongo DB. For that as a first step I need to create an index similar to below

      {{{}}
        "createIndexes": "<collection_name>",
        "indexes": [
          {
            "name": "<index_name>",
            "key": {
              "<path_to_property>": "cosmosSearch"
            },
            "cosmosSearchOptions": {
              "kind": "vector-ivf",
              "numLists": <integer_value>,
              "nProbes": <integer_value>,
              "similarity": "<string_value>",
              "dimensions": <integer_value>
      {{      }}}

      I want to do the same via MongoDB C# drivers. This is because I create the collection dynamically via code. I tried using the CreateIndexModelOptions. This class does not seem to have the properties required to create the above index. How do I go about doing this ?

       

      {{    }}}
        ]
      }
