• If you are trying to use Boolean operators, they must be ALL CAPS: tuyen ((tap truc) OR (tap tuc)) nha đe ((co trong) OR (cong trong)) va y te cong cong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tuyen ((tap truc) or (tap tuc)) nha đe ((co trong) OR (cong trong)) va y te cong cong".
• Adding a wildcard symbol may retrieve word variants: tuyen ((tap truc) or (tap tuc)) nha đe ((co trong) OR (cong trong)) va y te cong cong*.
