• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ky) OR (sai ky)) nang doc hoi. hieu ve ((pham thuc) OR (nham thuc)) dang hanh di cua te.
• Adding a wildcard symbol may retrieve word variants: tu ((sac ky) or (sai ky)) nang doc hoi. hieu ve ((pham thuc) or (nham thuc)) dang hanh di cua te*.
