I'm very new to MongoDb and I need to make a filter. I need to update all those fields 'value' property where the value is not null and where the value is not equal with the previous value

FilterDefinition<BsonDocument> filter =  Builders<BsonDocument>.Filter.And(

      Builders<BsonDocument>.Filter.Eq("field_id", kvp.Key), 

      Builders<BsonDocument>.Filter.Or( 

      Builders<BsonDocument>.Filter.Eq("value", ""),  

      Builders<BsonDocument>.Filter.Eq("value",previousValue)));



UpdateDefinition<BsonDocument> update = Builders<BsonDocument>.Update.Set("$.value", kvp.Value.Item2);



bulkCommands.Add(new UpdateManyModel<BsonDocument>(filter, update));

The filter returns all the elements, even where the value is null, and it updates that value, also.

I've tried to use this way:

var builder = Builders<BsonDocument>.Filter;

var filt = builder.Eq("field_id", kvp.Key) & builder.Eq("value", "");

but the same problem, the command updates all the entries, even where the value is null
