• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sang ky) OR (tang ky)) tang ha noi. hieu vu cham vuc van thanh ((san cua) OR (dan cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sang ky) or (tang ky)) tang ha noi. hieu vu cham vuc van thanh ((san cua) OR (dan cua)) tre".
