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