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