  In this note, we introduce and study a notion of bi-exactness for creation
operators acting on full, symmetric and anti-symmetric Fock spaces. This is a
generalization of our previous work, in which we studied the case of
anti-symmetric Fock spaces. As a result, we obtain new examples of solid
actions as well as new proofs for some known solid actions. We also study free
wreath product groups in the same context.
