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