• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) OR (toc sach)) ty ((lang ha) or (dang xay)) hoi. hieu van nam xuc ban hanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) ty ((lang ha) OR (dang xay)) hoi. hieu van nam xuc ban hanh vi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) ty ((lang ha) or (dang xay)) hoi. hieu van nam xuc ban hanh vi cuu tre*".
