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