• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang ma hoa. thi ((thanh cham) or (thanh pham)) ((soc va) OR (loc va)) dan sinh cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang ma hoa. thi ((thanh cham) OR (thanh pham)) ((soc va) OR (loc va)) dan sinh cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang ma hoa. thi ((thanh cham) or (thanh pham)) ((soc va) OR (loc va)) dan sinh cau treo".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang ma hoa. thi ((thanh cham) or (thanh pham)) ((soc va) OR (loc va)) dan sinh cau treo*.
