当我从elasticsearch删除索引时收到错误

Question

当我从elasticsearch手动删除索引时收到错误。手动删除后我会在路由中使用User.search函数。这是错误：

  

错误：[search_phase_execution_exception]所有分片都失败

我手动删除索引的原因是因为mongoosastic有一个已知的问题，每当我从mongodb删除文件时，elasticsearch仍然有文件。

这是代码

模型/ user.js的

var mongoose = require('mongoose');
var mongoosastic = require('mongoosastic');
var Schema = mongoose.Schema;

var UserSchema = new Schema({
  private: false,
  twitter: String,
  tokens: Array,
  username: String,
  displayName: String,
  picture: String,

});

UserSchema.plugin(mongoosastic, {
  hosts: [
    'localhost:9200'
  ]});

  module.exports = mongoose.model('User', UserSchema);

router.js

User.createMapping(function(err, mapping) {
    if (err) {
      console.log('error creating mapping (you can safely ignore this)');
      console.log(err);
    } else {
      console.log('mapping created!');
      console.log(mapping);
    }
  });


  var stream = User.synchronize();
  var count = 0;

  stream.on('data', function(err, doc){
    count++;
  });

  stream.on('close', function(){
    console.log('indexed ' + count + ' documents!');
  });

  stream.on('error', function(err){
    console.log(err);
  });

      /* The result for searching for User's */
  router.get('/search', function(req, res, next) {
    console.log(req.query.q);
    if (req.query.q) {
      User.search({
        query_string:
        { query: req.query.q }
      }, function(err, results) {
        if (err) return next(err);
        console.log(results);
        var data = results.hits.hits.map(function(hit) {
          return hit;
        });
        console.log(data);
        return res.render('main/search_results', { data: data });
      });
    }
  });
