• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((ty xang) or (ty hang)) xa hoi. hieu ve nhan luc va danh ((va cuu) OR (va chu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty xang) OR (ty hang)) xa hoi. hieu ve nhan luc va danh ((va cuu) OR (va chu)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty xang) or (ty hang)) xa hoi. hieu ve nhan luc va danh ((va cuu) OR (va chu)) tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((ty xang) or (ty hang)) xa hoi. hieu ve nhan luc va danh ((va cuu) OR (va chu)) tre*.
