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