lucene 建立索引的不同方式
1.创建一个简单的索引：
package lia.meetlucene; import java.io.File;
import org.apache.lucene.document.Document;
import org.apache.lucene.document.Field;
import org.apache.lucene.index.IndexWriter;
import org.apache.lucene.store.Directory;
import org.apache.lucene.store.FSDirectory;
import org.apache.lucene.util.Version;
import org.apache.lucene.analysis.standard.StandardAnalyzer; public class BasicIndexer {
public static void main(String[] args) throws java.io.IOException {
String indexDir = "C:/Users/Administrator/Desktop/xdj"; Directory dir = FSDirectory.open(new File(indexDir));
/*
* writer = new IndexWriter(dir, //3 创建Lucene Index Writer new
* StandardAnalyzer( //3 Version.LUCENE_30),//3 true, //3
* IndexWriter.MaxFieldLength.UNLIMITED); //3
*/
IndexWriter writer = new IndexWriter(dir, // 3 创建Lucene Index Writer
new StandardAnalyzer(Version.LUCENE_30),//
true, //
IndexWriter.MaxFieldLength.UNLIMITED); // 3 // Document
Document doc = new Document(); // Field -title
String title = "i love china";
Field field = new Field("title", title, Field.Store.YES,
Field.Index.ANALYZED);
// add field
doc.add(field); // Field -content
String content = "i love you, my mother land! ";
field = new Field("content", content, Field.Store.YES,
Field.Index.ANALYZED);
// add field
doc.add(field); // add document
writer.addDocument(doc); // close IndexWriter
writer.close(); // message
System.out.println("Index Created!");
}
}
2.创建一个复杂点的索引：
package lia.meetlucene; import java.io.File;
import org.apache.lucene.document.Document;
import org.apache.lucene.document.Field;
import org.apache.lucene.index.IndexWriter;
import org.apache.lucene.store.Directory;
import org.apache.lucene.store.FSDirectory;
import org.apache.lucene.util.Version;
import org.apache.lucene.analysis.standard.StandardAnalyzer; public class BasicIndexer {
public static void main(String[] args) throws java.io.IOException {
String indexDir = "C:/Users/Administrator/Desktop/xdj"; Directory dir = FSDirectory.open(new File(indexDir));
/*
* writer = new IndexWriter(dir, //3 创建Lucene Index Writer new
* StandardAnalyzer( //3 Version.LUCENE_30),//3 true, //3
* IndexWriter.MaxFieldLength.UNLIMITED); //3
*/
IndexWriter writer = new IndexWriter(dir, // 3 创建Lucene Index Writer
new StandardAnalyzer(Version.LUCENE_30),//
true, //
IndexWriter.MaxFieldLength.UNLIMITED); // 3 // 创建Document--1
Document doc = new Document(); // 创建Field -title
String title = "i love china";
Field field = new Field("title", title, Field.Store.YES,
Field.Index.NOT_ANALYZED);
// 添加add field
doc.add(field); // 创建Field -content
String content = "i love you, my mother land! ";
field = new Field("content", content, Field.Store.YES,
Field.Index.NOT_ANALYZED);
// 添加add field
doc.add(field); // 创建Field -time
String time = "2007-05-31";
field = new Field("time", time, Field.Store.YES, Field.Index.NO);
// 创建add field
doc.add(field); // 添加add document
writer.addDocument(doc); // 创建Document--2
doc = new Document(); // 创建Field -title
title = "i love mom";
field = new Field("title", title, Field.Store.YES,
Field.Index.NOT_ANALYZED);
// add field
doc.add(field); // 创建Field -content
content = "i love you, my mother! ";
field = new Field("content", content, Field.Store.YES,
Field.Index.NOT_ANALYZED);
// 添加add field
doc.add(field); // 创建Field -time
time = "2007-05-31";
field = new Field("time", time, Field.Store.YES, Field.Index.NO);
// 添加add field
doc.add(field); // 添加add document
writer.addDocument(doc); // 创建Document--3
doc = new Document(); // 创建Field -title
title = "i love xiaoyue";
field = new Field("title", title, Field.Store.YES,
Field.Index.NOT_ANALYZED);
// 添加add field
doc.add(field); // 创建Field -content
content = "i love you, my wife! ";
field = new Field("content", content, Field.Store.YES,
Field.Index.NOT_ANALYZED);
// 添加add field
doc.add(field); // 创建Field -time
time = "2007-05-31";
field = new Field("time", time, Field.Store.YES, Field.Index.NO);
// add field
doc.add(field); // 添加add document
writer.addDocument(doc); // 关闭close IndexWriter
writer.close(); // 提示message
System.out.println("Index Three Created!");
}
}
3.文件创建一个索引
package lia.meetlucene; import java.io.File;
import java.io.FileReader; import org.apache.lucene.document.Document;
import org.apache.lucene.document.Field;
import org.apache.lucene.index.IndexWriter;
import org.apache.lucene.store.Directory;
import org.apache.lucene.store.FSDirectory;
import org.apache.lucene.util.Version;
import org.apache.lucene.analysis.standard.StandardAnalyzer; public class BasicIndexer {
public static void main(String[] args) throws java.io.IOException {
String indexDir = "C:/Users/Administrator/Desktop/xdj"; Directory dir = FSDirectory.open(new File(indexDir));
/*
* writer = new IndexWriter(dir, //3 创建Lucene Index Writer new
* StandardAnalyzer( //3 Version.LUCENE_30),//3 true, //3
* IndexWriter.MaxFieldLength.UNLIMITED); //3
*/
IndexWriter writer = new IndexWriter(dir, // 3 创建Lucene Index Writer
new StandardAnalyzer(Version.LUCENE_30),//
true, //
IndexWriter.MaxFieldLength.UNLIMITED); // 3 // 创建Document
Document doc = new Document();
File f = new File(
"E:/xdj/tengxun/a_______________mm/2014-02-19 06.59.53.xml"); // 创建Field -name
String name = f.getName();
Field field = new Field("name", name, Field.Store.YES,
Field.Index.NOT_ANALYZED);
// 添加add field
doc.add(field); // 创建Field -content
field = new Field("content", new FileReader(f)); // FileText.getText(f);
// add field
doc.add(field); // 创建Field -path
String path = f.getPath();
field = new Field("path", path, Field.Store.YES, Field.Index.NO);
// 添加add field
doc.add(field); // 添加add document
writer.addDocument(doc); // 创建**************************************************************/
doc = new Document();
f = new File(
"E:/xdj/tengxun/a_______________mm/2014-02-04 11.43.01.xml"); // 创建Field -name
name = f.getName();
field = new Field("name", name, Field.Store.YES,
Field.Index.NOT_ANALYZED);
// add field
doc.add(field); // 创建Field -content
field = new Field("content", new FileReader(f));
// 添加add field
doc.add(field); // 创建Field -path
path = f.getPath();
field = new Field("path", path, Field.Store.YES, Field.Index.NO);
// 添加add field
doc.add(field); // 添加add document
writer.addDocument(doc); // 关闭close IndexWriter
writer.close(); // 提示message
System.out.println("File Index Created!");
}
}
