• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((tang ma) OR (mang may)) hoi. lieu van pham khoa va danh ((du cua) OR (dau cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((tang ma) or (mang may)) hoi. lieu van pham khoa va danh ((du cua) OR (dau cua)) tre".
• Adding a wildcard symbol may retrieve word variants: te sach y ((tang ma) or (mang may)) hoi. lieu van pham khoa va danh ((du cua) OR (dau cua)) tre*.
