• If you are trying to use Boolean operators, they must be ALL CAPS: (( chung thi quen vang. boi duong nguoi tay ) OR ( nhung thi quy lang. moi truong hoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( chung thi quen vang. boi duong nguoi tay ) or ( nhung thi quy lang. moi truong hoc mo ))*.
