Hi, in the post [http://www.elasticsearch.org/tutorials/2011/07/18/attachment-type-in-action.html](http://www.elasticsearch.org/tutorials/2011/07/18/attachment-type-in-action.html)  
,  
Attachment Type in Action ,

curl -X PUT "localhost:9200/test/attachment/\_mapping" -d '{  
"attachment" : {  
"properties" : {  
"file" : {  
"type" : "attachment",  
"fields" : {  
"title" : { "store" : "yes" },  
"file" : { "term\_vector":"with\_positions\_offsets",  
"store":"yes" }  
}  
}  
}  
}  
}'

curl "localhost:9200/\_search?pretty=true" -d '{  
"fields" : ["title"],  
"query" : {  
"query\_string" : {  
"query" : "amplifier"  
}  
},  
"highlight" : {  
"fields" : {  
"file" : {}  
}  
}  
}'
