I have an ES where I have indexed a bunch of files. Each file is tagged  
with a category field. I want to write Java code to get a list of all the  
categories. I am trying to do this using the terms aggregation:

QueryBuilder qb = QueryBuilders.matchAllQuery();  
SearchResponse sr =  
esClient.prepareSearch()  
.setQuery(qb)  
.setSize(20)  
.addAggregation(AggregationBuilders.terms("category\_names").field("category")).setSize(20)  
.execute()  
.actionGet();

Terms terms = sr.getAggregations().get("category\_names");  
int numCategories = terms.getBuckets().size();  
System.out.println("Number of category buckets found: "+ numCategories);

But this code always prints out that it found 10 category buckets. Yet, if  
I execute the following query in Sense:

GET files-index/file\_with\_category/\_search  
{  
"query": {  
"match\_all": {}  
},  
"aggs": {  
"categories": {  
"terms": {  
"field": "category",  
"size": 100  
}  
}  
}  
}

I get 18 category buckets. What am I doing wrong in the Java code?

Thx.

Alain

Hi,

You need to set the size on the terms aggregation:

AggregationBuilders.terms("category\_names").field("category").size(20)

Thx. That did the trick. I now realize that I was setting the size on the  
return value of addAggregation(), when in fact, I needed to set it on the  
return value of the field() method.
