• Performing a fuzzy search may retrieve terms with similar spellings: toc sach thu mang xa hoi. hieu ((va cao) or (va cac)) duc va ((hanh lai) OR (hanh tai)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach thu mang xa hoi. hieu ((va cao) OR (va cac)) duc va ((hanh lai) OR (hanh tai)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach thu mang xa hoi. hieu ((va cao) or (va cac)) duc va ((hanh lai) OR (hanh tai)) cua triet".
