• Performing a fuzzy search may retrieve terms with similar spellings: thuat ((sach ky) or (sach y)) nang xa hoi. ((hieu ve) OR (hieu va)) cao suc va hanh di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat ((sach ky) OR (sach y)) nang xa hoi. ((hieu ve) OR (hieu va)) cao suc va hanh di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((sach ky) or (sach y)) nang xa hoi. ((hieu ve) OR (hieu va)) cao suc va hanh di cua te".
• Adding a wildcard symbol may retrieve word variants: thuat ((sach ky) or (sach y)) nang xa hoi. ((hieu ve) OR (hieu va)) cao suc va hanh di cua te*.
