This paper proposes a fast and effective question-answer system for encyclopedia domain using a new answer indexing method. We define about 160 answer types. The indexer generates AIU(Answer Index Unit) structures between answer candidates and content words within LF(Logical Form) and sentence boundary. We select essential terms among question terms using syntactic information for ranking the answer candidates. Experiments show our new method is good for the encyclopedia question-answering system.
