• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sac ky) OR (sai ky)) nang x hoi. hieu ((ve cam) OR (ve cham)) luc va danh doi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sac ky) or (sai ky)) nang x hoi. hieu ((ve cam) OR (ve cham)) luc va danh doi cua tre".
• Adding a wildcard symbol may retrieve word variants: te ((sac ky) or (sai ky)) nang x hoi. hieu ((ve cam) OR (ve cham)) luc va danh doi cua tre*.
