• Performing a fuzzy search may retrieve terms with similar spellings: ((so sanh) OR (do sanh)) ky nang xa hoi. hieu va cam ((xuc va) OR (tuc va)) hanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sanh) OR (do sanh)) ky nang xa hoi. hieu va cam ((xuc va) OR (tuc va)) hanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: ((so sanh) OR (do sanh)) ky nang xa hoi. hieu va cam ((xuc va) OR (tuc va)) hanh vai cua tre*.
