• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((y nang) or (ky nang)) xa hoi. thien van lam xuc ((ban danh) OR (ban doanh)) lai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y nang) OR (ky nang)) xa hoi. thien van lam xuc ((ban danh) OR (ban doanh)) lai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y nang) or (ky nang)) xa hoi. thien van lam xuc ((ban danh) OR (ban doanh)) lai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y nang) or (ky nang)) xa hoi. thien van lam xuc ((ban danh) OR (ban doanh)) lai cua tre*.
