IndexFilterOperator Objects

class IndexFilterOperator(Enum)

[view_source]

Enumeration of operators available for filtering index records.

This enum defines the comparison operators that can be used when creating filters for searching and retrieving records from an index.

Attributes:

• EQUALS str - Equality operator ("==")
• NOT_EQUALS str - Inequality operator ("!=")
• CONTAINS str - Membership test operator ("in")
• NOT_CONTAINS str - Negative membership test operator ("not in")
• GREATER_THAN str - Greater than operator (">")
• LESS_THAN str - Less than operator ("<")
• GREATER_THAN_OR_EQUALS str - Greater than or equal to operator (">=")
• LESS_THAN_OR_EQUALS str - Less than or equal to operator ("<=")

IndexFilter Objects

This class defines a filter that can be used to search or retrieve records from an index based on specific field values and comparison operators.

Attributes:

• field str - The name of the field to filter on.
• value str - The value to compare against.
• operator Union[IndexFilterOperator, str] - The comparison operator to use.

__init__

def __init__(field: str, value: str, operator: Union[IndexFilterOperator,

Initialize a new IndexFilter instance.

Arguments:

• field str - The name of the field to filter on.
