• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ty) OR (sach thu)) ((nang xa) or (nang x)) hoi. hieu ve cac xuc va dinh de cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ty) OR (sach thu)) ((nang xa) OR (nang x)) hoi. hieu ve cac xuc va dinh de cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ty) OR (sach thu)) ((nang xa) or (nang x)) hoi. hieu ve cac xuc va dinh de cua te".
• Adding a wildcard symbol may retrieve word variants: su ((sach ty) OR (sach thu)) ((nang xa) or (nang x)) hoi. hieu ve cac xuc va dinh de cua te*.
