我正在使用orientdb并进行索引但我的索引引擎是sBTree我想将其更改为Lucene该做什么？

 public static void main(String[] args) throws IOException
        {       
            OrientGraph graph = null;

               try {

    OrientGraphFactory factory = new  OrientGraphFactory("plocal:/root/Progs/orientdbcommunity-1.7.10/databases/demotest11").setupPool(1,10);
                   graph=factory.getTx();
                graph.createIndex("number",Vertex.class);
                  graph.createIndex("age",Vertex.class);
                   graph.createIndex("type",Vertex.class);
                   graph.createIndex("location",Vertex.class);
                   graph.createIndex("name",Vertex.class);
                   graph.createIndex("time", Edge.class);
                   graph.createIndex("strength", Edge.class);
                   graph.createIndex("out", Edge.class);
                   BatchGraph bgraph = new BatchGraph(graph, VertexIDType.NUMBER, 700);
                   bgraph.setVertexIdKey("number");
                   bgraph.setLoadingFromScratch(true);                
                   Reader reader = new Reader();
                   List<String> inputList = reader.readFile();
                   InsertinDb insertdbobj = new InsertinDb();
                   long startTime = System.currentTimeMillis();
                   //System.out.println(startTime);
                   insertdbobj.insertinDb(bgraph,inputList);
                   long endTime = System.currentTimeMillis();

                   System.out.println("Time to insert" +(endTime - startTime));
                   graph.commit();
                 //  System.out.println(graph.countVertices());
                   System.out.println("success");
               } catch(OException e) {
                   System.out.println("no success - " + e.getMessage());

                   e.printStackTrace();
               } finally {
                   if(graph != null) {
                       graph.shutdown();
                   }
        }

        }

这是使用SBTree Engine索引的代码如何将索引引擎更改为lucene？请帮忙？

从图表Api中，您无法更改引擎。

但你可以执行一个命令来创建lucene索引，如下所示：

graph.getRawGraph().command(new OCommandSQL("create index V.name on V (name) FULLTEXT ENGINE LUCENE")).execute();

我正在使用orientdb并进行索引，但我的索引引擎是sBTree我想要将其更改为Lucene该怎么办？
