• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) or (so sach)) ly nang xa hoi. hieu ((ve coc) OR (ve co)) luc va thanh dam cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (so sach)) ly nang xa hoi. hieu ((ve coc) OR (ve co)) luc va thanh dam cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (so sach)) ly nang xa hoi. hieu ((ve coc) OR (ve co)) luc va thanh dam cua tre".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) or (so sach)) ly nang xa hoi. hieu ((ve coc) OR (ve co)) luc va thanh dam cua tre*.
