• Performing a fuzzy search may retrieve terms with similar spellings: so ((sach tay) OR (xach tay)) lang ha noi. hieu ((ve nam) or (le nam)) thuc va danh de cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sach tay) OR (xach tay)) lang ha noi. hieu ((ve nam) OR (le nam)) thuc va danh de cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sach tay) OR (xach tay)) lang ha noi. hieu ((ve nam) or (le nam)) thuc va danh de cua te".
• Adding a wildcard symbol may retrieve word variants: so ((sach tay) OR (xach tay)) lang ha noi. hieu ((ve nam) or (le nam)) thuc va danh de cua te*.
