• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty lang xa hoi. hieu va dao nuoc san anh ((vinh cuu) OR (((sinh cua) OR (sinh va)))) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty lang xa hoi. hieu va dao nuoc san anh ((vinh cuu) or (((sinh cua) OR (sinh va)))) tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ty lang xa hoi. hieu va dao nuoc san anh ((vinh cuu) or (((sinh cua) OR (sinh va)))) tre*.
