$not
Not
{"$not":{"field1":{"$eq":"value1"}}}

$eq
Match a single character string value
{"field1":{"$eq":"value1"}}
$ne
Exclude a single character string value
{"field1":{"$ne":"value1"}}

Value Type Expression

The numeric type of scalar index fields supports uint64, int64, and double. The operators supported by the numeric type in a Filter expression are shown in the following table.
Operator
Description
Example

Greater than
{"field1":{"$gt":123}}
$gte
Greater than or equal to

$lt
Less than
{"field1":{"$lt":123}}
$lte
Less than or equal to
{"field1":{"$lte":123}}
$ne
Not equal to
{"field1":{"$ne":123}}
$in
Matching any numeric value
{"field1":{"$in":[123,456]}}
$nin
Exclude all numeric values
{"field1":{"$nin":[123,456]}}

Supported Scalar Fields in Filters

Scalar data that every data object must have, specifically the fields supported by field1 and field2 mentioned above.
