I’m using ML8. I have a bunch of json documents in the database. Some documents have a certain property “summaryData”, something like:

{
...(other stuff)...
  summaryData: {
    count: 100,
    total: 10000,
    summaryDate: (date value)
  }
}

However, not all documents have this property. I’d like to construct an SJS query to retrieve those documents that don’t have this property defined. If it was SQL, I guess the equivalent would be something like “WHERE summaryData IS NULL”

I wasn’t sure what to search for in the docs. Any advise would be helpful.
