hello,  
I'm trying to use dynamic\_templates with a match\_mapping\_type of "object",  
and a mapping  
that suffixes the field name but leaves the type as object. Here my little  
sample script.

curl -XPUT '[http://localhost:9200/myindex](http://localhost:9200/myindex)'

body='{  
"mytype" : {  
"properties" : {  
"myroot" : {"type" : "object"}  
},  
"dynamic\_templates" : [  
{"mytemplate" : {  
"match" : "\*",  
"match\_mapping\_type" : "object",  
"mapping" : {  
"type" : "multi\_field",  
"fields" : {  
"{name}\_myext" : {"type": "object"}  
}  
}  
}}  
]  
}  
}'  
curl -XPUT '[http://localhost:9200/myindex/mytype/\_mapping](http://localhost:9200/myindex/mytype/_mapping)' -d "$body"

body='{"myroot" : {"myobj": {"name": "Victor  
Hugo"}}}'  
curl -XPOST '[http://localhost:9200/myindex/mytype](http://localhost:9200/myindex/mytype)' -d "$body"

When executing the script I see the following exception in the es log.

org.elasticsearch.index.mapper.MapperParsingException: No type specified  
for property [myobj\_myext]

What am I doing wrong here? Any hint appreciated.

thanks for your help,  
Michael

You can't replace an object type with a multi field type, it will cause  
failures to parse the data. Multi field mapping can only apply on "core"  
field types, no object ones.
