• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) OR (sach ty)) nang xa hoi. hieu qua ((cao xuc) or (cao duc)) xa nhanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach ty)) nang xa hoi. hieu qua ((cao xuc) OR (cao duc)) xa nhanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach ty)) nang xa hoi. hieu qua ((cao xuc) or (cao duc)) xa nhanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sach ty)) nang xa hoi. hieu qua ((cao xuc) or (cao duc)) xa nhanh vi cua te*.
