• Performing a fuzzy search may retrieve terms with similar spellings: tu cach tu ((nang xa) or (sang ma)) hoi. hieu ((ve cam) OR (ve cac)) duc va thanh lap cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cach tu ((nang xa) OR (sang ma)) hoi. hieu ((ve cam) OR (ve cac)) duc va thanh lap cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cach tu ((nang xa) or (sang ma)) hoi. hieu ((ve cam) OR (ve cac)) duc va thanh lap cua tre".
• Adding a wildcard symbol may retrieve word variants: tu cach tu ((nang xa) or (sang ma)) hoi. hieu ((ve cam) OR (ve cac)) duc va thanh lap cua tre*.
