thanks , it worked for me.
This would be useful for querying for past versions of documents that didn't have certain fields.
You can try the coalesce operator (double question mark ??). For example, to check if a Foo is undefined/null/false query.where(d.Foo == null || !(d.Foo ?? false))
For anyone who wants a Linq solution, it's: query.Where(d => !d.Foo.IsDefined()). To get the IsDefined extension method, you need to add "using Microsoft.Azure.Documents.SystemFunctions"
Query documents that don't have fields defined? Select * from docs d where d.Foo = Undefined.
Does this also work for the mongodb api?
Response from @DocuemntDB on twitter we will be adding ISDEFINED to the SQL Query Grammar at some point. ISUNDEFINED will be the functional equivalent of that UDF.
function isUndefined(input, property)
Select * from docs d where NOT is_defined(d.Foo)
How can we improve Azure Cosmos DB?

Use temporary user defined function to solve problem.
