Value from/to for two fields

The “Value from/to for two fields” filter rule (package filter_range) filters items based on a value range defined by two separate attributes. The first attribute represents the start value (“from”), the second attribute the end value (“to”). An item is included in the result when a given search value lies within the range defined by both attribute values.

Typical use cases: Validity periods (“Valid from” / “Valid until”), price ranges with separate fields for minimum and maximum price, or event periods.
