Aggregation module - value_count clarification/problem

[watsindename]

Hi,

I am trying to get the unique number of values for a given field. From my 
understanding of 
"value_count"
 
it counts the number of values that are extracted from the aggregated 
documents. After the steps in es-agg-test-1.sh, and on querying for unique 
values of field "k" the response that I get is 

{
   "took": 16,
   "timed_out": false,
   "_shards": {
  "total": 5,
  "successful": 5,
  "failed": 0
   },
   "hits": {
  "total": 20,
  "max_score": 1,
  "hits": [] //deleted content of "hits" to shorten the paste
   },
   "aggregations": {
  "k_count": {
 "value": 22
  }
   }
}

How can I be getting "value" 22, shouldn't it be 20 as thats the number of 
unique "k" values in documents.

Another example, on querying for unique values of field "t" I get the 
following response

{
   "took": 7,
   "timed_out": false,
   "_shards": {
  "total": 5,
  "successful": 5,
  "failed": 0
   },
   "hits": {
  "total": 20,
  "max_score": 1,
  "hits": [] //deleted content of "hits" to shorten the paste
   },
   "aggregations": {
  "k_count": {
 "value": 20
  }
   }
}

Again, shouldn't the "value" be 1, as the only value of "t" is 23 in all 
documents.
