1. create mapping
   curl -XPUT localhost:9200/index1/
   curl localhost:9200/index1/Parent/_mapping?pretty -d '
   {
   "Parent" : {
   "_all" : {
   "enabled" : false
   },
   "_source" : {
   "compress" : true
   },
   "properties" : {
   "_tenantid" : {
   "type" : "long",
   "store" : "yes"
   },
   "age" : {
   "type" : "long"
   },
   "name" : {
   "type" : "string"
   },
   "sex" : {
   "type" : "string"
   }
   }
   }
   }
   '
   curl localhost:9200/index1/Child/_mapping?pretty -d '
   {
   "Child" : {
   "_all" : {
   "enabled" : false
   },
   "_parent" : {
   "type" : "Parent"
   },
   "_routing" : {
   "required" : true
   },
   "_source" : {
   "compress" : true
   },
   "properties" : {
   "_tenantid" : {
   "type" : "long",
   "store" : "yes"
   },
   "age" : {
   "type" : "long"
   },
   "name" : {
   "type" : "string"
   },
   "shangshi" : {
   "type" : "boolean"
   }
   }
   }
   }
   '
2. Query

curl localhost:9200/index1/Parent/_search?pretty -d '
{ "sort" : [{ "age" : {"order" : "desc"} }],"query": { "filtered": { "query": { "has_child": { "type": "Child", "query": { "query_string": { "query": "+_tenantid:100002 +(-age:20)"} } } },
"filter": { "fquery": { "query": { "query_string": { "query": "+_tenantid:100002 +(name:dog OR age:[10 TO 2147483647])" } }, "_cache": true } } } } }
'

OK, no result found, of course

1. Index one doc in an irrelevant type

curl localhost:9200/index1/Type1/key0 -d '
{"_tenantid": 100002, "name": "lilei", "age": -2, "sex": "f", "marry": false, "weight": 2.3, "height": 2.7E+23, "grade": 123, "bill": -120, "fee": 245, "money": 3453, "number": 65333,
"phone": 4200000000, "small": 123.123456789123456789, "birthday": 20120306000000}
'

1. Exactly the same query again

curl localhost:9200/index1/Parent/_search?pretty -d '
{ "sort" : [{ "age" : {"order" : "desc"} }],"query": { "filtered": { "query": { "has_child": { "type": "Child", "query": { "query_string": { "query": "+_tenantid:100002 +(-age:20)"} } } },
"filter": { "fquery": { "query": { "query_string": { "query": "+_tenantid:100002 +(name:dog OR age:[10 TO 2147483647])" } }, "_cache": true } } } } }
'

Now, NullPointerException!
