• Performing a fuzzy search may retrieve terms with similar spellings: su ((((sach ty) OR (xach tay))) or (sach thu)) xang xa hoi. lieu van dau thuc van hanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((((sach ty) OR (xach tay))) OR (sach thu)) xang xa hoi. lieu van dau thuc van hanh vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((((sach ty) OR (xach tay))) or (sach thu)) xang xa hoi. lieu van dau thuc van hanh vi cua tre*".
