• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((((ty nang) OR (ly nang))) OR (ky nang)) xa hoi. hieu van hanh xu va danh di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((((ty nang) OR (ly nang))) or (ky nang)) xa hoi. hieu van hanh xu va danh di cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((((ty nang) OR (ly nang))) or (ky nang)) xa hoi. hieu van hanh xu va danh di cua tre*.
