• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) OR (vu sach)) y ((dang xay) or (lang ha)) hoi. hieu qua hai xuc va dan vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) y ((dang xay) OR (lang ha)) hoi. hieu qua hai xuc va dan vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) y ((dang xay) or (lang ha)) hoi. hieu qua hai xuc va dan vai cua tre*".
