Hello all,

I've tested with versions 1.0.0, 1.1.0 and 1.1.1 and the size property  
doesn't seam to work.

The following works using facets:  
{  
"size": "0",  
"facets": {  
"facettest": {  
"terms": {  
"field": "somefield",  
"size": "5"  
}  
}  
}  
}

The response contains 5 terms as expected, but changing to aggregations:

{  
"size": "0",  
"aggs": {  
"aggtest": {  
"terms": {  
"field": "somefield",  
"size": "5"  
}  
}  
}  
}

Return an 400 error message ending with "Parse Failure [Unknown key for a  
VALUE\_STRING in [aggtest]: [size].]]; }]".

Is there any special requirement or configuration for this to work? The  
documentation talks about this property since some time in  
[http://www.elasticsearch.org/guide/en/elasticsearch/reference/master/search-aggregations-bucket-terms-aggregation.html#\_size\_amp\_shard\_size](http://www.elasticsearch.org/guide/en/elasticsearch/reference/master/search-aggregations-bucket-terms-aggregation.html#_size_amp_shard_size)  
but doesn't actually show an usage example.

Cheers,  
Oswaldo

Solved.

Over the irc channel the user @honzakral showed me a working example he had  
and I noticed that for aggregations, the size property cannot be quoted.

On the line of the previous examples, this works:

{  
"size": "1",  
"aggs": {  
"tags": {  
"terms": {  
"field": "usrIdHost",  
"size": 1  
}  
}  
}  
}

Opened a ticket so this inconsistency can be checked:
