• Performing a fuzzy search may retrieve terms with similar spellings: ((nuoc sach) or (nguoi san)) ly hoang xa hoi. hieu ((ve cam) OR (ve cac)) xuc ban thanh day cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((nuoc sach) OR (nguoi san)) ly hoang xa hoi. hieu ((ve cam) OR (ve cac)) xuc ban thanh day cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nuoc sach) or (nguoi san)) ly hoang xa hoi. hieu ((ve cam) OR (ve cac)) xuc ban thanh day cua tre".
• Adding a wildcard symbol may retrieve word variants: ((nuoc sach) or (nguoi san)) ly hoang xa hoi. hieu ((ve cam) OR (ve cac)) xuc ban thanh day cua tre*.
