• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) OR (tu sach)) ky nang xa hoi. lieu va lam ((xuc va) or (truc va)) hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (tu sach)) ky nang xa hoi. lieu va lam ((xuc va) OR (truc va)) hanh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) OR (tu sach)) ky nang xa hoi. lieu va lam ((xuc va) or (truc va)) hanh vai cua te".
• Adding a wildcard symbol may retrieve word variants: ((thu sach) OR (tu sach)) ky nang xa hoi. lieu va lam ((xuc va) or (truc va)) hanh vai cua te*.
