• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sach v nang xa hoi. hieu va cam luc ((ban thanh) or (ban hang)) ((ve cuu) OR (ve chu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach v nang xa hoi. hieu va cam luc ((ban thanh) OR (ban hang)) ((ve cuu) OR (ve chu)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach v nang xa hoi. hieu va cam luc ((ban thanh) or (ban hang)) ((ve cuu) OR (ve chu)) tre".
