• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (thu sach)) ky ((nang xa) or (lang xa)) hoi. hieu ve cham xuc van hanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ky ((nang xa) OR (lang xa)) hoi. hieu ve cham xuc van hanh vi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (thu sach)) ky ((nang xa) or (lang xa)) hoi. hieu ve cham xuc van hanh vi cuu tre*".
