Lucene学习

Lucene使用主要有以下步骤

1建立索引

2搜索

3获得结果

附上简单的测试代码

package test;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;import org.apache.lucene.index.Term;import org.apache.lucene.search.Hits;import org.apache.lucene.search.IndexSearcher;import org.apache.lucene.search.Query;import org.apache.lucene.search.TermQuery;public class test{private static String INDEX_STORE_PATH = "e:\\index";public static void main(String args[]) throws IOException{//建立索引

                  IndexWriter writer=new IndexWriter(INDEX_STORE_PATH,new StandardAnalyzer(),true);writer.setUseCompoundFile(false);Document doc1=new Document();Document doc2=new Document();Document doc3=new Document();Field f1=new Field("bookname","钢铁",Field.Store.YES,Field.Index.TOKENIZED);Field f2=new Field("bookname","女英雄",Field.Store.YES,Field.Index.TOKENIZED);Field f3=new Field("bookname","女儿",Field.Store.YES,Field.Index.TOKENIZED);doc1.add(f1);doc2.add(f2);doc3.add(f3);writer.addDocument(doc1);writer.addDocument(doc2);writer.addDocument(doc3);writer.close();//建立查询IndexSearcher searcher=new IndexSearcher(INDEX_STORE_PATH);Term t1=new Term("bookname","女");Query q1=new TermQuery(t1);//BooleanQuery query=new BooleanQuery();//query.add(q1,BooleanClause.Occur.MUST);Hits hits =searcher.search(q1);for(int i=0;i<hits.length();i++){System.out.println(hits.doc(i));System.out.println(hits.score(i));}}}
