• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach xa) OR (sach dao)) ve giai ((((hoan hoang) or (luan hoan))) or (quan hoang)) minh~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach xa) OR (sach dao)) ve giai ((((hoan hoang) OR (luan hoan))) OR (quan hoang)) minh.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach xa) OR (sach dao)) ve giai ((((hoan hoang) or (luan hoan))) or (quan hoang)) minh".
• Adding a wildcard symbol may retrieve word variants: tu ((sach xa) OR (sach dao)) ve giai ((((hoan hoang) or (luan hoan))) or (quan hoang)) minh*.
