• If you are trying to use Boolean operators, they must be ALL CAPS: (((("thi hinh van dinh f.c.") OR ("thi tinh va dinh chau."))) OR ("them hanh kem tinh hoc."))~.
• Removing quotes may allow a broader search: (((( thi hinh van dinh f.c. ) or ( thi tinh va dinh chau. ))) or ( them hanh kem tinh hoc. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thi hinh van dinh f.c.") or ("thi tinh va dinh chau."))) or ("them hanh kem tinh hoc."))*.
