• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang co hoc. thien va cham ((xuc va) or (duc va)) ((hanh lam) OR (hanh kem)) chau tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang co hoc. thien va cham ((xuc va) OR (duc va)) ((hanh lam) OR (hanh kem)) chau tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang co hoc. thien va cham ((xuc va) or (duc va)) ((hanh lam) OR (hanh kem)) chau tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang co hoc. thien va cham ((xuc va) or (duc va)) ((hanh lam) OR (hanh kem)) chau tre*.
