• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty ang xa hoi. hieu ((ve cham) or (vu cham)) thuc ((va hanh) OR (va danh)) vai cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ang xa hoi. hieu ((ve cham) OR (vu cham)) thuc ((va hanh) OR (va danh)) vai cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ang xa hoi. hieu ((ve cham) or (vu cham)) thuc ((va hanh) OR (va danh)) vai cau tren".
• Adding a wildcard symbol may retrieve word variants: te sach ty ang xa hoi. hieu ((ve cham) or (vu cham)) thuc ((va hanh) OR (va danh)) vai cau tren*.
