• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thuat san)) ky nganh xay hoi. thi van cam luc va thanh ((hai cuu) OR (hai chu)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thuat san)) ky nganh xay hoi. thi van cam luc va thanh ((hai cuu) OR (hai chu)) tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thuat san)) ky nganh xay hoi. thi van cam luc va thanh ((hai cuu) OR (hai chu)) tre*.
