• Performing a fuzzy search may retrieve terms with similar spellings: so sach ky nang xa hoi. hieu ((ve cam) OR (ve cham)) tuc ((xa huong) or (va huong)) doi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky nang xa hoi. hieu ((ve cam) OR (ve cham)) tuc ((xa huong) OR (va huong)) doi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky nang xa hoi. hieu ((ve cam) OR (ve cham)) tuc ((xa huong) or (va huong)) doi cua tre".
• Adding a wildcard symbol may retrieve word variants: so sach ky nang xa hoi. hieu ((ve cam) OR (ve cham)) tuc ((xa huong) or (va huong)) doi cua tre*.
