• Performing a fuzzy search may retrieve terms with similar spellings: tu sach phu lang xa hoi. hieu ((vien cac) OR (vien da)) xuc ((va danh) or (ban hanh)) vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach phu lang xa hoi. hieu ((vien cac) OR (vien da)) xuc ((va danh) OR (ban hanh)) vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach phu lang xa hoi. hieu ((vien cac) OR (vien da)) xuc ((va danh) or (ban hanh)) vai cua tre*".
