• Performing a fuzzy search may retrieve terms with similar spellings: ((so canh) OR (bo canh)) may nang xa hoi. hieu ve phan thuc day ((hanh vai) or (hanh va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so canh) OR (bo canh)) may nang xa hoi. hieu ve phan thuc day ((hanh vai) OR (hanh va)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so canh) OR (bo canh)) may nang xa hoi. hieu ve phan thuc day ((hanh vai) or (hanh va)) cua tre*".
