• Performing a fuzzy search may retrieve terms with similar spellings: hoc anh thi hanh xa hoi. hieu va ((cac tuc) or (cac toc)) ((xa hanh) OR (xa khanh)) vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc anh thi hanh xa hoi. hieu va ((cac tuc) OR (cac toc)) ((xa hanh) OR (xa khanh)) vai cua triet.
