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