• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ((y lang) OR (_ lang)) hoa hoi. thien van cac ((xuc va) or (tuc va)) hanh hai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ((y lang) OR (_ lang)) hoa hoi. thien van cac ((xuc va) OR (tuc va)) hanh hai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ((y lang) OR (_ lang)) hoa hoi. thien van cac ((xuc va) or (tuc va)) hanh hai cua te".
• Adding a wildcard symbol may retrieve word variants: vu sach ((y lang) OR (_ lang)) hoa hoi. thien van cac ((xuc va) or (tuc va)) hanh hai cua te*.
