# Fields that Do Not Exist or Contain No Value

## EMPTY

The `EMPTY` field specifier (case sensitive) allows you to find documents in which a specified field does not exist or contains no value.

    FieldText=EMPTY{}:yourFields

where:

`yourFields` | is one or more fields. A document returns only if it does not contain any of these fields or if these fields are empty. To specify multiple fields, separate them with colons (there must be no space before or after a colon).

Examples:

    FieldText=EMPTY{}:ID

A document must not contain an `ID` field, or must hold no value in its `ID` field, to return.

    FieldText=EMPTY{}:ID:Name

A document must not contain an `ID` or `Name` field, or must hold no value in its `ID` or `Name` field, to return.
