Limit aggregations to list of values - elasticsearch

Question

Can I limit aggregations to return only specific list of values? I have something like this:
{ "aggs" : {
"province" : {
"terms" : {
"field" : "province"
}
}
},
"query": {
"bool": {
//my query..
But let's say I know list of province for which I want make count ({'province1', 'province2', 'province3'}). Is it possible to restrict returned list of province without influence on my query results?
I want to get:
//list of hits..
//
"aggregations": {
"province": {
"buckets": [
{
"key": "province1",
"doc_count": 200
},
{
"key": "province2",
"doc_count": 162
},
{
"key": "province3",
"doc_count": 162
}
// even if there is more possible provinces
// I don't want to see them

Answer 1

Sure, just use term filters.
Here's an example. Let's say I have visit stats for a bunch of different IP addresses, but I only want to get counts of document for two of them, I could do this:
POST /test_index/_search?search_type=count
{
"aggregations": {
"ip": {
"terms": {
"field": "ip",
"size": 10,
"include": [
"146.233.189.126",
"193.33.153.89"
]
}
}
}
}
and get back something like:
{
"took": 4,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"failed": 0
},
"hits": {
"total": 7,
"max_score": 0,
"hits": []
},
"aggregations": {
"ip": {
"doc_count_error_upper_bound": 0,
"sum_other_doc_count": 0,
"buckets": [
{
"key": "146.233.189.126",
"doc_count": 3
},
{
"key": "193.33.153.89",
"doc_count": 3
}
]
}
}
}
Here is some code I used to play around with it:

So your example might look like:
{
"aggs": {
"province": {
"terms": {
"field": "province",
"include": [
"province1",
"province2",
"province3"
]
}
}
}
}
