不想LDA有现成的代码，像工具一样看可以直接调用。Luence相当于是一个工具包，将具体的步骤需要自己完成。恩。。还是看视频比较系统

简单的建立索引：

public static void main(String[] args)throws Exception{
        String [] ids={"1","2","3"};
        String [] names={"heh","btb","ee"};
        String [] addr={"bupt","thu","sjtu"};
        Analyzer analyzer=new StandardAnalyzer();
        String index="D:/Users/huaiyu/Workspaces/luenceindex";
        Directory dir=FSDirectory.getDirectory(index);
        IndexWriter writer=new IndexWriter(dir,analyzer,true,IndexWriter.MaxFieldLength.LIMITED);
        for(int i=0;i<ids.length;i++){
           org.apache.lucene.document.Document doc=new org.apache.lucene.document.Document();
           doc.add(new org.apache.lucene.document.Field("id",ids[i],org.apache.lucene.document.Field.Store.YES,org.apache.lucene.document.Field.Index.ANALYZED));
           doc.add(new org.apache.lucene.document.Field("name",names[i],org.apache.lucene.document.Field.Store.NO,org.apache.lucene.document.Field.Index.ANALYZED));
           doc.add(new org.apache.lucene.document.Field("addr",addr[i],org.apache.lucene.document.Field.Store.YES,org.apache.lucene.document.Field.Index.ANALYZED));
           writer.addDocument(doc);

        }
        writer.optimize();
        writer.close();
}
