• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sai ky) OR (cac ky)) nang xa hoi. hieu van cam duc van anh ((va cua) OR (via cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sai ky) or (cac ky)) nang xa hoi. hieu van cam duc van anh ((va cua) OR (via cua)) te".
• Adding a wildcard symbol may retrieve word variants: thu ((sai ky) or (cac ky)) nang xa hoi. hieu van cam duc van anh ((va cua) OR (via cua)) te*.
