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