• Performing a fuzzy search may retrieve terms with similar spellings: tu sach tu dong xa hoi. hieu ve ((cham duc) or (pham duy)) va ((hanh dao) OR (thanh dat)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tu dong xa hoi. hieu ve ((cham duc) OR (pham duy)) va ((hanh dao) OR (thanh dat)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tu dong xa hoi. hieu ve ((cham duc) or (pham duy)) va ((hanh dao) OR (thanh dat)) cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sach tu dong xa hoi. hieu ve ((cham duc) or (pham duy)) va ((hanh dao) OR (thanh dat)) cua triet*.
