• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach ky) or (sai ky)) dang tay hoi. hieu ve cac bo tuan ((anh via) OR (anh bia)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ky) OR (sai ky)) dang tay hoi. hieu ve cac bo tuan ((anh via) OR (anh bia)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ky) or (sai ky)) dang tay hoi. hieu ve cac bo tuan ((anh via) OR (anh bia)) cua tre*".
