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