• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (thu sach)) ky nang van hoc. hieu van lam xuc va hanh vai ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (thu sach)) ky nang van hoc. hieu van lam xuc va hanh vai ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (thu sach)) ky nang van hoc. hieu van lam xuc va hanh vai ((cua tre) OR (cuu tre))".
