• Performing a fuzzy search may retrieve terms with similar spellings: toc ((sach ty) or (sach y)) nang xa hoi. lieu ((va cam) OR (va cham)) luc va dinh duc cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach ty) OR (sach y)) nang xa hoi. lieu ((va cam) OR (va cham)) luc va dinh duc cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ty) or (sach y)) nang xa hoi. lieu ((va cam) OR (va cham)) luc va dinh duc cuu tre".
• Adding a wildcard symbol may retrieve word variants: toc ((sach ty) or (sach y)) nang xa hoi. lieu ((va cam) OR (va cham)) luc va dinh duc cuu tre*.
