• Performing a fuzzy search may retrieve terms with similar spellings: su sach lo nang xa hoi. hieu ((ve cham) OR (vu cham)) luc va dan ((do cua) or (de cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach lo nang xa hoi. hieu ((ve cham) OR (vu cham)) luc va dan ((do cua) OR (de cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach lo nang xa hoi. hieu ((ve cham) OR (vu cham)) luc va dan ((do cua) or (de cua)) te*".
