• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ly) OR (sach lo)) van xa hoi. hieu ((va cac) or (va cao)) xuc va thanh phan cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ly) OR (sach lo)) van xa hoi. hieu ((va cac) OR (va cao)) xuc va thanh phan cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ly) OR (sach lo)) van xa hoi. hieu ((va cac) or (va cao)) xuc va thanh phan cua tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ly) OR (sach lo)) van xa hoi. hieu ((va cac) or (va cao)) xuc va thanh phan cua tre*.
