• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky ((tang ha) OR (trung ha)) noi. hieu vu cham vuc van thanh ((le cua) OR (de cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky ((tang ha) OR (trung ha)) noi. hieu vu cham vuc van thanh ((le cua) or (de cua)) tre".
• Adding a wildcard symbol may retrieve word variants: thu sac ky ((tang ha) OR (trung ha)) noi. hieu vu cham vuc van thanh ((le cua) or (de cua)) tre*.
