I have a field that looks like this: "Address": "3478 GLAMORGAN RD". Using Elasticsearch 2.3.1

When using the match\_phrase\_prefix query on the \_all field with a single term, nothing will be returned  
Example:  
{  
"match\_phrase\_prefix":{  
"\_all": "glamor"  
}  
}

Using the profile=true option I can see that this is generating the following Lucene query:  
{  
"query\_type":"TermQuery",  
"lucene":"\_all:glamor",  
...  
}

Of course this does not match anything because there is no term "glamor".

When using the match\_phrase\_prefix query on the Address field with a single term, the expected results are returned.  
Example:  
{  
"match\_phrase\_prefix":{  
"Address": "gl"  
}  
}

Using the profile=true option I can see that this is generating the following Lucene query:  
{  
"query\_type":"BooleanQuery",  
"lucene":"attributes.Address:glenelg attributes.Address:glynnwood attributes.Address:glamorgan",  
...  
"children":[  
{  
"query\_type":"TermQuery",  
"lucene":"attributes.Address:glenelg",  
...  
},  
{  
"query\_type":"TermQuery",  
"lucene":"attributes.Address:glynnwood",  
...  
},  
{  
"query\_type":"TermQuery",  
"lucene":"attributes.Address:glamorgan",  
...  
}  
]  
}

I have tried increasing the max expansion parameter, but this did not help. The query on the \_all field will work just fine when using more than one term.  
Example:  
{  
"match\_phrase\_prefix":{  
"\_all": "3478 glamor"  
}  
}

Any idea why a single term cannot be used to prefix match when using the \_all field?

I see this was bug that was fixed in Elasticsearch 2.4.2
