• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach lo) OR (sach doi)) nang ma hoi. hieu ve cham xuc va ((thanh vien) or (hanh vi)) cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach lo) OR (sach doi)) nang ma hoi. hieu ve cham xuc va ((thanh vien) OR (hanh vi)) cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach lo) OR (sach doi)) nang ma hoi. hieu ve cham xuc va ((thanh vien) or (hanh vi)) cau tren".
• Adding a wildcard symbol may retrieve word variants: tu ((sach lo) OR (sach doi)) nang ma hoi. hieu ve cham xuc va ((thanh vien) or (hanh vi)) cau tren*.
