• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((thien dang) or (tien anh)) - ((hanh tang) OR (hanh mang)) luat trong cong te han tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thien dang) OR (tien anh)) - ((hanh tang) OR (hanh mang)) luat trong cong te han tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thien dang) or (tien anh)) - ((hanh tang) OR (hanh mang)) luat trong cong te han tap*".
