I'm running an aggregation and getting the top 5 results. When I run the
exact same aggregation on the top 50 results I'm getting totally different
results. I expect that when asking for 50 the top 5 should remain the same
and an additional 45 should be added to the list. That is not what's
happening.
Note: I'm aggregating on the non_analyzed part of a multi-field
authInput.userName, I'm not sure if that makes a difference or not.
*Here is my query: *
GET prodstarbucks/authEvent/_search
{
"size": 0,
"aggs": {
"users": {
"terms": {
"field": "authInput.userName.userNameNotAnalyzed",
"size": 5
}
}
},
"query": {
"filtered": {
"query": {
"match_all": {}
},
"filter": {
"bool": {
"must": [
{
"range": {
"authResult.authEventDate": {
"gte": "2014-10-01T00:00:00.000",
"lte": "2014-10-31T00:00:00.000"
}
}
}
]
}
}
}
}
}
*RESULT:*
{
"took": 2171,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 1090455,
"max_score": 0,
"hits": []
},
"aggregations": {
"users": {
"buckets": [
{

},
{
"key": "3982EC96-DB4C-4A22-AC64-2CFC09D52579",
"doc_count": 68
},
{
"key": "674E6691-8A46-4D34-BB31-B78780969311",
"doc_count": 24
},
{

},
{
"key": "{7CB63FEE-709A-4AD5-AA16-2CFE3282FEE8}",
"doc_count": 23
}
]
}
}
}
If I change the aggregation size to be 50, these are my top 5 results:
{
"took": 2256,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 1090501,
"max_score": 0,
"hits": []
},
"aggregations": {
"users": {
"buckets": [
{
"key": "3D64E4FD-6D25-4E77-966E-A0E059CFD31E",
"doc_count": 109
},
{
"key": "3982EC96-DB4C-4A22-AC64-2CFC09D52579",
"doc_count": 84
},
{
"key": "F77E8291-1640-4C3F-8A1A-D6D955AB940A",
"doc_count": 59
},
{
"key": "6AC1ED48-8F91-400B-9353-172BB6E1823B",
"doc_count": 53
},
{
"key": "52CDF454-92C2-4C32-91F6-AF4F08C8F908",
"doc_count": 52
},
...
The doc_counts are all different. Can someone help explain this to me and
let me know how I might get the correct doc_count even when only asking for
the top 5 results.
Thank you!
