• Performing a fuzzy search may retrieve terms with similar spellings: so sanh ky ((nang ma) or (sang ma)) hoi. hieu ve cam buc ((xa huong) OR (xa muong)) dan cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh ky ((nang ma) OR (sang ma)) hoi. hieu ve cam buc ((xa huong) OR (xa muong)) dan cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh ky ((nang ma) or (sang ma)) hoi. hieu ve cam buc ((xa huong) OR (xa muong)) dan cua tre*".
