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