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