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