Hi all! Im currently trying to use the inner\_hits functionality that was  
added in elasticsearch 1.5. Unfortunately, elastic is throwing an  
ArrayOutOfBoundsException when running my query. I would be very grateful  
if someone can have a look and tell me what I am doing wrong, as I feel  
that I have followed the documentation correctly.

Example that produces the problem:

curl -XPOST '[http://localhost:9200/twitter](http://localhost:9200/twitter)'

curl -XPOST '[http://localhost:9200/twitter/\_mapping/tweet](http://localhost:9200/twitter/_mapping/tweet)' -d '  
{  
"tweet": {  
"properties": {  
"comments": {  
"properties": {  
"messages": {  
"type": "nested",  
"properties": {  
"message": {  
"type" : "string",  
"index": "not\_analyzed"  
}  
}  
}  
}  
}  
}  
}  
}'

curl -XPOST '[http://localhost:9200/twitter/tweet](http://localhost:9200/twitter/tweet)' -d '  
{  
"comments": {  
"messages": [  
{"message": "Nice website"},  
{"message": "Worst ever"}  
]  
}  
}'

curl -XGET '[http://localhost:9200/twitter/tweet/\_search](http://localhost:9200/twitter/tweet/_search)' -d '  
{  
"query": {  
"nested": {  
"path": "comments.messages",  
"query": {  
"match": {"comments.messages.message": "Nice website"}  
},  
"inner\_hits" : {}  
}  
}  
}'

Response:

{"took":54,"timed\_out":false,"\_shards":{"total":5,"successful":4,"failed":1,"failures":[{"index":"twitter","shard":4,"status":500,"reason":"ArrayIndexOutOfBoundsException[-1]"}]},"hits":{"total":1,"max\_score":1.4054651,"hits":[]}}

Note that the query will work if I take "inner\_hits" out.
