• Performing a fuzzy search may retrieve terms with similar spellings: te sach ly vang ((xa hoi) or (mai hoi)). thieu nien ((cac tuc) OR (cac toc)) va hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly vang ((xa hoi) OR (mai hoi)). thieu nien ((cac tuc) OR (cac toc)) va hanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly vang ((xa hoi) or (mai hoi)). thieu nien ((cac tuc) OR (cac toc)) va hanh vi cua triet*".
