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