• Performing a fuzzy search may retrieve terms with similar spellings: su sach thu hang xa hoi. hieu ((ve cai) or (((ve cham) OR (vu cham)))) duc van hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thu hang xa hoi. hieu ((ve cai) OR (((ve cham) OR (vu cham)))) duc van hanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thu hang xa hoi. hieu ((ve cai) or (((ve cham) OR (vu cham)))) duc van hanh vi cua triet*".
