The name of a Lua script that defines a function with the name "pred". The function specifies conditions to judge a record or record pair against. The function returns a Boolean value; the engine's response to the function result depends on the engine.
| Engine type | Engine response if the function returns true |
|---|---|
| And | The record pair is included in the engine output track. |
| AndNot | The record in the first track is discarded. (Records from the second track are never included in the output anyway.) |
| AndNotThen | The record in the first track is discarded. (Records from the second track are never included in the output anyway.) |
| AndThen | The record pair is included in the engine output track. |
| Deduplicate | The second record is discarded. |
| Filter | The record is included in the engine output track. |
