i'm experimenting w/ the nested mapping type and am looking a lots of  
examples / blog posts and not seeing any way to specify core types for the  
fields in nested documents -- am I missing something or is this not  
possible?

Cheers,

David

You can use core types in nested fields of course. Here is an example that  
hopefully will clear-up things:

"mappings": {  
"my\_index": {  
"properties": {  
"attributes": {  
"type": "nested",  
"dynamic": "false",  
"properties": {  
"attribute\_id": {  
"type": "long"  
},  
"attribute\_name": {  
"type": "string"  
},  
"attribute\_values": {  
"type": "string"  
}  
}  
}  
}  
}  
}

and notice that dynamic flag is set to false so no other extra field would  
be added to the attributes field.
