• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty lang xa hoi. hieu ((((ve cam) or (va cac))) or (ve cac)) quoc gia thanh ve chu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty lang xa hoi. hieu ((((ve cam) OR (va cac))) OR (ve cac)) quoc gia thanh ve chu tre.
• Adding a wildcard symbol may retrieve word variants: te sach ty lang xa hoi. hieu ((((ve cam) or (va cac))) or (ve cac)) quoc gia thanh ve chu tre*.
