• Performing a fuzzy search may retrieve terms with similar spellings: te sach tu ((((nang xa) OR (mang xa))) or (nang x)) hoi. hieu va cham soc ban hang sinh cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tu ((((nang xa) OR (mang xa))) OR (nang x)) hoi. hieu va cham soc ban hang sinh cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tu ((((nang xa) OR (mang xa))) or (nang x)) hoi. hieu va cham soc ban hang sinh cua tre*".
