• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((ty hang) or (tay lang)) xa hoi. hieu van cam ((xuc va) OR (luc va)) nhanh ha cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty hang) OR (tay lang)) xa hoi. hieu van cam ((xuc va) OR (luc va)) nhanh ha cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty hang) or (tay lang)) xa hoi. hieu van cam ((xuc va) OR (luc va)) nhanh ha cua viet".
• Adding a wildcard symbol may retrieve word variants: te sach ((ty hang) or (tay lang)) xa hoi. hieu van cam ((xuc va) OR (luc va)) nhanh ha cua viet*.
