• Performing a fuzzy search may retrieve terms with similar spellings: te sach y dang van hoi. lieu va nam thuc va hanh va ((cua triet) or (((cuu tre) OR (cau tren))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y dang van hoi. lieu va nam thuc va hanh va ((cua triet) OR (((cuu tre) OR (cau tren)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y dang van hoi. lieu va nam thuc va hanh va ((cua triet) or (((cuu tre) OR (cau tren))))".
• Adding a wildcard symbol may retrieve word variants: te sach y dang van hoi. lieu va nam thuc va hanh va ((cua triet) or (((cuu tre) OR (cau tren))))*.
