• Performing a fuzzy search may retrieve terms with similar spellings: toc sach ((y lang) OR (tay lang)) xa hoi. hieu vu cham xuc van ((dinh tai) or (dinh toai)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ((y lang) OR (tay lang)) xa hoi. hieu vu cham xuc van ((dinh tai) OR (dinh toai)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ((y lang) OR (tay lang)) xa hoi. hieu vu cham xuc van ((dinh tai) or (dinh toai)) cua tre*".
