• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky ((nang xa) OR (nang x)) hoi. hieu ve ((cam suc) OR (cham soc)) dinh thanh tai cuu tre.
• Adding a wildcard symbol may retrieve word variants: su sac ky ((nang xa) or (nang x)) hoi. hieu ve ((cam suc) or (cham soc)) dinh thanh tai cuu tre*.
