• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ((v nang) OR (van nang)) xa hoi. hieu van ban xuc va thanh ((lam cua) or (lam chat)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((v nang) OR (van nang)) xa hoi. hieu van ban xuc va thanh ((lam cua) OR (lam chat)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((v nang) OR (van nang)) xa hoi. hieu van ban xuc va thanh ((lam cua) or (lam chat)) triet".
• Adding a wildcard symbol may retrieve word variants: thu sach ((v nang) OR (van nang)) xa hoi. hieu van ban xuc va thanh ((lam cua) or (lam chat)) triet*.
