• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((nang ma) OR (tang ma)) hoi. ((lieu ha) or (liem ha)) nam thuc xay hanh tai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((nang ma) OR (tang ma)) hoi. ((lieu ha) OR (liem ha)) nam thuc xay hanh tai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((nang ma) OR (tang ma)) hoi. ((lieu ha) or (liem ha)) nam thuc xay hanh tai cuu tre*".
