Hy,

I have a problem with fields having the same name as known types. For  
example, I have the following mapping:

{  
"ip\_info" : {  
"properties" : {  
"lat" : {"type" : "double"},  
"long" : {"type" : "double"}  
}  
}  
}

I put the following docs in this field:

{  
"lat":42.3535,  
"long":32.35544545  
}

{  
"lat":41.3535,  
"long":32.35544545  
}

{  
"lat":41.3535,  
"long":32.15544545  
}

When I try to do a top on these fields, the lat is working very good:  
{"aggs":{"top-tags":{"terms":{"field":"lat","size":3}}}}

returns:  
{  
aggregations: {  
top-tags: {  
buckets: [  
{  
key: 41.3535  
doc\_count: 2}  
{  
key: 42.3535  
doc\_count: 1}]}}  
}

But when I try to do a top on "long", the following message is thrown:  
{

- error: ReduceSearchPhaseException[Failed to execute phase [fetch],  
[reduce] ]; nested:  
ClassCastException[org.elasticsearch.search.aggregations.bucket.terms.DoubleTerms$Bucket  
cannot be cast to  
org.elasticsearch.search.aggregations.bucket.terms.LongTerms$Bucket];
- status: 503

}

I'm using elasticsearch 1.1.1.

What I'm doing wrong?

Thaank you,

Hi,

I have tried to reproduce your issue on both the master branch and on  
version 1.1.1 but both seem to work as expected. The commands I ran are in  
the following gist:  
[https://gist.github.com/colings86/d67e00c378ee28c4485a](https://gist.github.com/colings86/d67e00c378ee28c4485a)

Could you have a look at let me know if I misunderstood something about  
your problem?

Colin

Yes, that are the commands that should reproduce this.

If on your version works ok, that my question is why on my setup doing a  
top on long field returns the error (

- error: ReduceSearchPhaseException[Failed to execute phase [fetch],  
[reduce] ]; nested:  
ClassCastException[org.elasticsearch.search.aggregations.bucket.terms.DoubleTerms$Bucket  
cannot be cast to  
org.elasticsearch.search.aggregations.bucket.terms.LongTerms$Bucket];

)

Basically, ES tries to convert the fields from double to long. Why is doing  
this?

I am not sure why your setup is producing this issue. To help to diagnose  
the cause could you please post the mappings for the index (see [1] for how  
to do this) and the complete cURL command for your search request?

Thanks

Colin
