Hello,  
I am tring to use versioning feature as increment counter. I got  
documents like {"event":"event1"} and i put them when and event  
happens, so every time i put version is incremented.

I can search that index and i use version as event counter.

One response is:  
{  
"\_index" : "events",  
"\_type" : "counter",  
"\_id" : "97",  
"\_version" : 3814,  
"\_score" : 1.0, "\_source" : {"event": "event1"}  
}

Here i use 3814 as counter.

But i would like to do a facet too. Like

{  
"version":  
true,  
"query" :  
{  
"match\_all":  
{ }  
},  
"facets":  
{  
"ms":  
{  
"terms\_stats":  
{  
"key\_field":  
"event",  
"value\_script":  
"doc.\_version"  
}  
}  
}  
}

I get  
Query Failed [Failed to execute main query]]; nested:  
PropertyAccessException[[Error: could not access: \_version; in class:  
org.elasticsearch.search.lookup.DocLookup]\n[Near : {...  
doc.\_version ....}]\n ^\n[Line: 1, Column: 1]]

How can i access version of a document in facet?

Thanks

Version is not exposed as a "doc" value in scripts. Open an issue, can be added (though requires some thought, and if the realtime value should be exposed or the "last refresh" value).
