然而，Elasticsearch产生的文档我不知道它们来自哪里：

curl http://localhost:9200/portal_development/_search?pretty=true -d  '
{

        "from" : 0, "size" : 20,

      "query" : {
         "query_string" : {
           "query" : "2:*"
          }
        }
    }'

{
  "took" : 33,
  "timed_out" : false,
  "_shards" : {
    "total" : 5,
    "successful" : 5,
    "failed" : 0
  },
  "hits" : {
    "total" : 53,
    "max_score" : 1.0,
    "hits" : [ {
      "_index" : "portal_development",
      "_type" : "portal_development",
      "_id" : "Document-3744",
      "_score" : 1.0, "_source" : {...
      }, {
      "_index" : "portal_development",
      "_type" : "portal_development",
      "_id" : "Document-3751",
      "_score" : 1.0, "_source" : {...
    }, {
      "_index" : "portal_development",
      "_type" : "portal_development",
      "_id" : "Document-3732",
      "_score" : 1.0, "_source" : {
    } ]
  }
}

这到底是怎么回事？什么可能导致这种情况？
