I'm seeing duplicate concatenated values when using the combo analyzer for  
\_all using a multi-field defined in a dynamic template.

e.g. Instead of seeing "Foo Bar" when listing the \_all terms aggregation,  
I'm seeing "Foo Bar Foo Bar" for the token because my mulit-field defines 2  
sub-fields. If the multi-field is defined with 4 sub-fields, then "Foo Bar"  
is concatenated 4 times.

My set up is below.

_Elasticsearch 1.0.0 on CentOs 6.4 with Java 1.7.0\_51._

_$ES\_HOME/config/default-mapping.json:_  
{  
"_default_": {  
"\_all": {  
"enabled": true,  
"analyzer": "combo",  
"store": false  
},  
"dynamic\_templates": {  
"string\_multifield\_template": {  
"match": "\*",  
"match\_mapping\_type": "string",  
"mapping": {  
"include\_in\_all": false,  
"fields": {  
"{name}": {  
"index": "not\_analyzed",  
"store": true,  
"type": "string"  
},  
"lowercase": {  
"analyzer": "lowercase",  
"index": "analyzed",  
"store": false,  
"type": "string"  
}  
}  
}  
}  
}  
}  
}

_$ES\_HOME/config/elasticsearch.yml:_  
...  
index.analysis.analyzer.lowercase.type: custom  
index.analysis.analyzer.lowercase.tokenizer: keyword  
index.analysis.analyzer.lowercase.filter [lowercase]

index.analysis.analyzer.combo.type: custom  
index.analysis.analyzer.combo.sub\_analyzers: [keyword, lowercase]  
index.analysis.analyzer.combo.deduplication: true  
index.analysis.analyzer.combo.tokenstream\_reuse: false  
...

The aggregation query I use is the following:  
{  
"aggs": {  
"\_all": {  
"terms": {  
"field": "\_all"  
}  
}  
}  
}

Thoughts?
