• Performing a fuzzy search may retrieve terms with similar spellings: toc ((sach tu) or (cach tu)) ngang cho hoc. hieu ve cac xuc van hanh ((vi cua) OR (vai cua)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach tu) OR (cach tu)) ngang cho hoc. hieu ve cac xuc van hanh ((vi cua) OR (vai cua)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach tu) or (cach tu)) ngang cho hoc. hieu ve cac xuc van hanh ((vi cua) OR (vai cua)) cau*".
