• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sang ky) OR (dang ky)) lang ha noi. hieu vu cham xuc van ((tuan vien) or (tuan kien)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sang ky) OR (dang ky)) lang ha noi. hieu vu cham xuc van ((tuan vien) OR (tuan kien)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sang ky) OR (dang ky)) lang ha noi. hieu vu cham xuc van ((tuan vien) or (tuan kien)) cua tre".
• Adding a wildcard symbol may retrieve word variants: thu ((sang ky) OR (dang ky)) lang ha noi. hieu vu cham xuc van ((tuan vien) or (tuan kien)) cua tre*.
