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