Getting value of component in Query

[QuentinLeCaignec]

Is it possible to check/filter for a specific value in a Query?

I might be approaching this wrong, but I have a component that references the ID of another entity, so I can "link" an entity to another or at least have a reference to another entity.
In my system, I'd like to get an entity that contains a component "Location", this component contains an ID referencing another entity's component (for example entity A with component Location.ID = "place-1" is contained within entity B with component Place of ID "place-1"), and I would like to filter for this.
In my example, I want to grab all entities that have components referencing a specific entity+component, basically get all things that are contained within a specific entity.

Maybe this is not the right approach for ECS? Is there a cleaner way to have components link to or reference other components so I can easily grab one from the other?
