• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach le) OR (sach lo)) van xay hoi. hieu ((va cam) or (va cham)) luc va hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach le) OR (sach lo)) van xay hoi. hieu ((va cam) OR (va cham)) luc va hanh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach le) OR (sach lo)) van xay hoi. hieu ((va cam) or (va cham)) luc va hanh vai cua te".
• Adding a wildcard symbol may retrieve word variants: thu ((sach le) OR (sach lo)) van xay hoi. hieu ((va cam) or (va cham)) luc va hanh vai cua te*.
