生成的索引文件.fnm中所包含了Document的所有Field名称。

如图就是生成索引，打开所显示的文件。

package segment;

import java.io.IOException;
import org.apache.lucene.analysis.standard.StandardAnalyzer;
import org.apache.lucene.document.Document;
import org.apache.lucene.document.Field;
import org.apache.lucene.index.IndexWriter;

public class Segment {

private String INDEX_PATH = "E:\\Lucene项目\\索引文件";
Document doc1 = null;
Document doc2 = null;
public Segment(){

try
{ doc1 = new Document();
Field f1 = new Field("name1", "smi steve ted teddy terry", Field.Store.YES, Field.Index.TOKENIZED);
Field f2 = new Field("name2", "what are you doing", Field.Store.YES, Field.Index.TOKENIZED);
Field f3 = new Field("name3", "how do you do", Field.Store.YES, Field.Index.TOKENIZED);
doc1.add(f1);
doc1.add(f2);
doc1.add(f3);

doc2 = new Document();
Field f4 = new Field("name4", "smi steve ted teddy terry", Field.Store.YES, Field.Index.TOKENIZED);
Field f5 = new Field("name4", "what are you doing", Field.Store.YES, Field.Index.TOKENIZED);
doc2.add(f4);
doc2.add(f5);

IndexWriter writer = new IndexWriter(INDEX_PATH, new StandardAnalyzer(), true);
writer.setUseCompoundFile(false);
writer.addDocument(doc1);
writer.addDocument(doc2);
writer.close();
}catch(IOException e){
e.printStackTrace();

}
}

public static void main(String[] args) {
// TODO Auto-generated method stub
Segment se = new Segment();

}

}
