• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc ((sach ky) or (sach y)) ((nang xa) OR (lang xa)) hoi. hieu chi cham tuc va hanh lam chat tre~".
• Adding a wildcard symbol may retrieve word variants: thuoc ((sach ky) or (sach y)) ((nang xa) OR (lang xa)) hoi. hieu chi cham tuc va hanh lam chat tre*.
