• Performing a fuzzy search may retrieve terms with similar spellings: ((toc sach) OR (doc sach)) thuat nang xa hoi. hieu va cam luc va ((hanh vai) or (hanh vi)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc sach) OR (doc sach)) thuat nang xa hoi. hieu va cam luc va ((hanh vai) OR (hanh vi)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc sach) OR (doc sach)) thuat nang xa hoi. hieu va cam luc va ((hanh vai) or (hanh vi)) cua tre".
