Session: Querying: How to Use NOT Operator

IDocumentQuery contains NOT operator which can be used to negate next predicate

Example I

// load all entities from 'Employees' collection
// where firstName NOT equals 'Robert'
const employees = await session.advanced
    .documentQuery({ collection: "Employees" })
    .not()
    .whereEquals("FirstName", "Robert")
    .all();

Example II

// load all entities from 'Employees' collection
// where firstName NOT equals 'Robert'
// and lastName NOT equals 'King'
const employees = await session.advanced
    .documentQuery({ collection: "Employees" })
    .not()
    .openSubclause()
    .whereEquals("FirstName", "Robert")
    .andAlso()
    .whereEquals("LastName", "King")
    .closeSubclause()
    .all();

Example III

// load all entities from 'Employees' collection
// where firstName NOT equals 'Robert'
// and lastName NOT equals 'King'
// identical to 'Example II' but 'whereNotEquals' is used
const employees = await session.advanced
    .documentQuery({ collection: "Employees" })
    .whereNotEquals("FirstName", "Robert")
    .andAlso()
    .whereNotEquals("LastName", "King")
    .all();
