Any help would be appreciated. I have a parent document that has an array  
of sub documents which are tags that are associated with an objectid which  
is used to identify another element. I am able to search on the tags and  
get a response which returns the parent document which is exactly what I  
want. However, since the tags map to an objectid, I'd like to know which  
keywords matched the tag so I can get the objectid. I can compare the tags  
on the client to figure out which matched, however, if using a stemming  
analyzer, this wouldn't work and I'd like to find a better way if possible.  
For example, if I search for "friend and families" I would get a return of  
the document with id 249184, but I want to find out that we matched a tag  
related to objectid='7'. Any suggestions on if I'm going in the right  
direction to get the results I need or would there be another way to  
structure this.

{  
"\_index": "myindex",  
"\_type": "mytype",  
"\_id": "249184",  
"\_version": 1,  
"\_score": 1,  
"\_source": {  
"id": 249184,  
"info":"I love elasticsearch",  
"mytags": [  
{  
"objectid": 7,  
"tags": [  
"friend and families",  
"brother"  
]  
},  
{  
"objectid": 3,  
"tags": [  
"sister"  
]  
}  
]  
}  
}

The index is defined as follows (has been simplified for this example):

{  
"mydata": {  
"properties": {  
"id": {  
"type": "integer",  
"index": "not\_analyzed"  
},  
"info": {  
"type": "string",  
"analyzer": "standard"  
},  
"mytags": {  
"type" : "object",  
"properties": {  
"objectid": { "type": "integer", "index":  
"not\_analyzed" },  
"tags": { "type": "string", "analyzer": "standard"}  
}  
}  
}  
}  
}

Thanks much
