• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (te sach)) thi hang va hoi. hieu ((ve cam) OR (ve cham)) xuc va tinh ha cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) thi hang va hoi. hieu ((ve cam) OR (ve cham)) xuc va tinh ha cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) thi hang va hoi. hieu ((ve cam) OR (ve cham)) xuc va tinh ha cua viet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (te sach)) thi hang va hoi. hieu ((ve cam) OR (ve cham)) xuc va tinh ha cua viet*.
