• Performing a fuzzy search may retrieve terms with similar spellings: so sach ty hang va hoi. hieu ve cam tuc ((((va huong) OR (va tuong))) or (va thuong)) doi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty hang va hoi. hieu ve cam tuc ((((va huong) OR (va tuong))) OR (va thuong)) doi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty hang va hoi. hieu ve cam tuc ((((va huong) OR (va tuong))) or (va thuong)) doi cuu tre".
• Adding a wildcard symbol may retrieve word variants: so sach ty hang va hoi. hieu ve cam tuc ((((va huong) OR (va tuong))) or (va thuong)) doi cuu tre*.
