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