• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang xa hoi. lieu va ((lam duoc) or (dat duoc)) ((ban thanh) OR (ban hang)) vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang xa hoi. lieu va ((lam duoc) OR (dat duoc)) ((ban thanh) OR (ban hang)) vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang xa hoi. lieu va ((lam duoc) or (dat duoc)) ((ban thanh) OR (ban hang)) vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang xa hoi. lieu va ((lam duoc) or (dat duoc)) ((ban thanh) OR (ban hang)) vai cuu tre*.
