Hi,
I am trying to get the unique number of values for a given field. From my
understanding of "value_counthttp://www.elasticsearch.org/guide/en/elasticsearch/reference/master/search-aggregations-metrics-valuecount-aggregation.html"
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.
