• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((y nang) or (ly nang)) xa hoi. hieu ve cam tuc ban thanh ((va chua) OR (ca chua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((y nang) OR (ly nang)) xa hoi. hieu ve cam tuc ban thanh ((va chua) OR (ca chua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((y nang) or (ly nang)) xa hoi. hieu ve cam tuc ban thanh ((va chua) OR (ca chua)) triet".
• Adding a wildcard symbol may retrieve word variants: su sach ((y nang) or (ly nang)) xa hoi. hieu ve cam tuc ban thanh ((va chua) OR (ca chua)) triet*.
