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