Filtering can be done by using the WHERE clause. The conditions we add in the clause will cause DocumentDB to filter the collection, and any document must evaluate the specified conditions to be true, otherwise they will not be part of the result set. To demonstrate several operators in the WHERE clause, our current PersonInformation document will be expanded with several properties. The support C# solution from Chapter 3, Basic Querying, will be upgraded with this new requirement:
Every document will contain an indicator on how many devices this specific person has at home to support home automation
An additional subtree containing the actual home automation devices including the price of the device will be added
This section will demonstrate multiple operators for the WHERE clause:
Binary operators
The BETWEEN keyword
Logical operators
The IN keyword
Conditional expressions
