Class org.apache.lucene.index.IndexReader

Examples of org.apache.lucene.index.IndexReader.document()

org.apache.lucene.index.IndexReader.document()
Returns the stored fields of the n^th Document in this index.
NOTE: for performance reasons, this method does not check if the requested document is deleted, and therefore asking for a deleted document may yield unspecified results. Usually this is not required, however you can call {@link #isDeleted(int)} with the requested document ID to verifythe document is not deleted. @throws CorruptIndexException if the index is corrupt @throws IOException if there is a low-level IO error
