• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((y lang) OR (tay lang)) xa hoi. ((thien van) or (thi van)) nam qua van hanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y lang) OR (tay lang)) xa hoi. ((thien van) OR (thi van)) nam qua van hanh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y lang) OR (tay lang)) xa hoi. ((thien van) or (thi van)) nam qua van hanh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((y lang) OR (tay lang)) xa hoi. ((thien van) or (thi van)) nam qua van hanh vi cua tre*.
