How can I filter by nested properties in OData?

I came across the following answer while reading up on questions related to mine:
Nested filter on Data Transfer Object using OData Wep Api

Funny thing is, I never came across that question in my previous searches on SO. Otherwise I wouldn't have to ask this question. Anyway this method works for me:

http://localhost:62559/Home/Read?$filter=Territories/any(c:%20c/TerritoryDescription eq 'Wilton')

Assume that you have a nested JSON Array Object like this and have to apply Odata filters on the below batters/topping keys, then you have to use a / to refer to the key.

For example, you have to select batters id - The syntax would beFilter: batters/id eq '1001' ; batters/type ne 'Chocolate'

{"id": "0001","type": "Cook Cake","name": "Customized","batters":            [                { "id": "1001", "type": "Regular" },                { "id": "1002", "type": "Chocolate" },                { "id": "1003", "type": "Blueberry" },                { "id": "1004", "type": "Devil's Food" }            ],"topping":    [        { "id": "5001", "type": "None" },        { "id": "5002", "type": "Glazed" },        { "id": "5005", "type": "Sugar" },        { "id": "5007", "type": "Powdered Sugar" },        { "id": "5006", "type": "Chocolate with Sprinkles" },        { "id": "5003", "type": "Chocolate" },        { "id": "5004", "type": "Maple" }    ]}
