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