• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((y nang) or (v nang)) xa hoi. hieu ve chat luc va ((thanh hai) OR (thanh phan)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y nang) OR (v nang)) xa hoi. hieu ve chat luc va ((thanh hai) OR (thanh phan)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) or (v nang)) xa hoi. hieu ve chat luc va ((thanh hai) OR (thanh phan)) cua tre*".
