# IndexWriter Class

An IndexWriter creates and maintains an index. The third argument to the constructor determines whether a new index is created, or whether an existing index is opened for the addition of new documents. In either case, documents are added with the addDocument method. When finished adding documents, close should be called. If an index will not have more documents added for a while and optimal search performance is desired, then the optimize method should be called before the index is closed.

For a list of all members of this type, see IndexWriter Members.
