• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty ((hang ca) OR (hang tai)) hoi. hieu ve cham xuc va hanh lai ((dua tren) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty ((hang ca) OR (hang tai)) hoi. hieu ve cham xuc va hanh lai ((dua tren) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty ((hang ca) OR (hang tai)) hoi. hieu ve cham xuc va hanh lai ((dua tren) or (cuu tre))*".
