• Performing a fuzzy search may retrieve terms with similar spellings: tuyen tai cac kieu đe co ban ((((ve y) or (ve ky))) or (ke ky)) ((te cong) OR (tai cong)) luong~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tuyen tai cac kieu đe co ban ((((ve y) OR (ve ky))) OR (ke ky)) ((te cong) OR (tai cong)) luong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tuyen tai cac kieu đe co ban ((((ve y) or (ve ky))) or (ke ky)) ((te cong) OR (tai cong)) luong".
• Adding a wildcard symbol may retrieve word variants: tuyen tai cac kieu đe co ban ((((ve y) or (ve ky))) or (ke ky)) ((te cong) OR (tai cong)) luong*.
