• Performing a fuzzy search may retrieve terms with similar spellings: ((su sac) or (su sach)) ky danh xa hoi. hieu van cac qua dan ((dung cua) OR (dung cho)) chua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su sach)) ky danh xa hoi. hieu van cac qua dan ((dung cua) OR (dung cho)) chua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su sach)) ky danh xa hoi. hieu van cac qua dan ((dung cua) OR (dung cho)) chua triet".
• Adding a wildcard symbol may retrieve word variants: ((su sac) or (su sach)) ky danh xa hoi. hieu van cac qua dan ((dung cua) OR (dung cho)) chua triet*.
