• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ky tang) OR (ky nang)) xa hoi. hieu van chat xuc va ((han tai) OR (nhan tai)) va thieu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky tang) or (ky nang)) xa hoi. hieu van chat xuc va ((han tai) OR (nhan tai)) va thieu*".
