Complex classes like ActiveQuery often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes. You can also have a look at the cohesion graph to spot any un-connected, or weakly-connected components.
Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.
While breaking up the class, it is a good idea to analyze how other classes use ActiveQuery, and based on these observations, apply Extract Interface, too.

||
| 369 | * can be used to modify the relation queries on-the-fly as the array value. |
||
| 370 | * - If a relation query does not need modification, you may use the relation name as the array value. |
||

||
| 372 | * The relation name may optionally contain an alias for the relation table (e.g. `books b`). |
||
| 373 | * |

||
| 375 | * |
||

||
