• Performing a fuzzy search may retrieve terms with similar spellings: ((te sac) or (((te cac) OR (te cao)))) ky nang x hoi. hieu qua am thuc va lanh dan cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (((te cac) OR (te cao)))) ky nang x hoi. hieu qua am thuc va lanh dan cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) or (((te cac) OR (te cao)))) ky nang x hoi. hieu qua am thuc va lanh dan cua tre".
• Adding a wildcard symbol may retrieve word variants: ((te sac) or (((te cac) OR (te cao)))) ky nang x hoi. hieu qua am thuc va lanh dan cua tre*.
