• Performing a fuzzy search may retrieve terms with similar spellings: tu sach xa nang ma hoi. hieu ((ve cam) or (va cam)) xuc van ((hang hai) OR (hoang hai)) chau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach xa nang ma hoi. hieu ((ve cam) OR (va cam)) xuc van ((hang hai) OR (hoang hai)) chau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach xa nang ma hoi. hieu ((ve cam) or (va cam)) xuc van ((hang hai) OR (hoang hai)) chau treo*".
