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