• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach ngon khong he đong luc ) or ( thu sach ((phap chong) OR (phap cong)) khi đong luc ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ngon khong he đong luc ) OR ( thu sach ((phap chong) OR (phap cong)) khi đong luc )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach ngon khong he đong luc ) or ( thu sach ((phap chong) OR (phap cong)) khi đong luc ))".
• Adding a wildcard symbol may retrieve word variants: (( tu sach ngon khong he đong luc ) or ( thu sach ((phap chong) OR (phap cong)) khi đong luc ))*.
