• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) OR (vu sach)) tai lang xa hoi. thien van lam duoc va trinh ((di cuu) or (dinh cuu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) tai lang xa hoi. thien van lam duoc va trinh ((di cuu) OR (dinh cuu)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) tai lang xa hoi. thien van lam duoc va trinh ((di cuu) or (dinh cuu)) tre".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (vu sach)) tai lang xa hoi. thien van lam duoc va trinh ((di cuu) or (dinh cuu)) tre*.
