• Performing a fuzzy search may retrieve terms with similar spellings: te sach tu nang ma hoi. hieu ((((qua cam) OR (qua cai))) or (qua cac)) luc va hang doi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tu nang ma hoi. hieu ((((qua cam) OR (qua cai))) OR (qua cac)) luc va hang doi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tu nang ma hoi. hieu ((((qua cam) OR (qua cai))) or (qua cac)) luc va hang doi cua te*".
