• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) ky nang xa hoi. hieu va chat xuc va thanh va luu (tru* OR truc*).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) ky nang xa hoi. hieu va chat xuc va thanh va luu (tru* or truc*)".
• Adding a wildcard symbol may retrieve word variants: ((te sach) OR (toc sach)) ky nang xa hoi. hieu va chat xuc va thanh va luu (tru* or truc*)*.
