Lucene的简单应用

照着baidu写着Lucene的例子&＃xff0c;突然发现new PaodingAnalyzer()不是Lucene包下的类&＃xff0c;一查才知道他是paoding解牛的一个用于Lucene的工具,提供中文支持的&＃xff0c;需要加入jar包&＃xff1a;paoding-analysis.jar。其中要把该jar包中的paoding-dic-home.properties文件中的paoding.dic.home写成paoding.dic.home&＃61;F:\\jar\\Paoding\\dic形式&＃xff08;别忘了把注解去了&＃xff09;。dic为解压的dic文件夹。

创建索引例子代码如下&＃xff1a;

package lucene;import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.io.Reader;import org.apache.lucene.analysis.Analyzer;
import org.apache.lucene.analysis.standard.StandardAnalyzer;
import org.apache.lucene.document.Document;
import org.apache.lucene.document.Field;
import org.apache.lucene.index.CorruptIndexException;
import org.apache.lucene.index.IndexWriter;
import org.apache.lucene.store.LockObtainFailedException;public class IndexWriterTest {public static final String indexDir &＃61; "src//core//scratch//";public static final String dataDir &＃61; "src//lucene//index//";public static void main(String[] args) throws FileNotFoundException,IOException,CorruptIndexException,LockObtainFailedException {File indexFile &＃61; new File(indexDir);Analyzer luceneAnalyzer &＃61; new StandardAnalyzer();IndexWriter indexWriter &＃61; new IndexWriter(dataDir, luceneAnalyzer, true);for(File file : indexFile.listFiles()){Reader reader &＃61; new FileReader(file);Document document &＃61; new Document();document.add(new Field("path",file.getCanonicalPath(), Field.Store.YES,Field.Index.UN_TOKENIZED));document.add(new Field("contents", reader));indexWriter.addDocument(document);}indexWriter.optimize();indexWriter.close();System.out.println("complete...");}
}

查询代码如下&＃xff1a;
