• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (hoc sach)) ((thu nang) OR (thu bang)) xa hoi. hieu va cham sac van hanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (hoc sach)) ((thu nang) OR (thu bang)) xa hoi. hieu va cham sac van hanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (hoc sach)) ((thu nang) OR (thu bang)) xa hoi. hieu va cham sac van hanh vai cua tre*.
