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