• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky dang van hoi. hieu ((ve chat) OR (van chat)) xuc ((va thanh) or (may tinh)) va luu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky dang van hoi. hieu ((ve chat) OR (van chat)) xuc ((va thanh) OR (may tinh)) va luu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky dang van hoi. hieu ((ve chat) OR (van chat)) xuc ((va thanh) or (may tinh)) va luu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky dang van hoi. hieu ((ve chat) OR (van chat)) xuc ((va thanh) or (may tinh)) va luu tre*.
