• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) or (toc sach)) ty hang xa hoi. thien van cam xuc va dinh ((lam cua) OR (nam cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) ty hang xa hoi. thien van cam xuc va dinh ((lam cua) OR (nam cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (toc sach)) ty hang xa hoi. thien van cam xuc va dinh ((lam cua) OR (nam cua)) tre*".
