• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ly) OR (sac ky)) va xac hoi. ((hieu va) OR (hieu van)) cac luc va hang tai cuu tre~.
• Adding a wildcard symbol may retrieve word variants: tu ((sac ly) or (sac ky)) va xac hoi. ((hieu va) or (hieu van)) cac luc va hang tai cuu tre*.
