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