in terminal you will see between other things the folow mensage ``BUILD SUCCESS``
* After that you need to install the plugin...

```
```bash
sudo /path_to_elastichsearch/bin/plugin --url file:///path_to_the_project/target/releases/streaming-aggregation-1.0-SNAPSHOT.zip --install streaming-aggregation

sudo service elasticsearch restart
```
#How to use
* First you need to create a 'query' with aggregations like the folow with the parameter 'createContext=true'
```bash
curl -XGET 'http://localhost:9200/index_name/_streaming_aggregation?createContext=true' -d '
{
"size": 0,
"query" : {
"filtered" : {
"query" : { "match_all" : {}},
"filter" : {
"range" : {
"postDate" : { "from" : "2011-12-10", "to" : "2011-12-12" }
}
}
}
},
"aggs" : {
"sum_price" : { "sum" : { "field" : "price" }}
}
}'
```
* This request will return a ID like the folow
```
search1443144481695
```
All others request will need this ID
To get the aggregated(actual) value you can make a GET request
```
curl -XGET 'http://localhost:9200/index_name/_streaming_aggregation?pretty=true&id=search1443144481695'
```
Response sample:
```
{
"took" : 3,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 8,
"max_score" : 0.0,
"hits" : [ ]
},
"aggregations" : {
"min_price" : {
"value" : 201.0,
"value_as_string" : "201.0"
}
}
}
```
To each new document (or on some change in a document) you shuld call the follow request
```bash
curl -XPUT 'http://localhost:9200/index_name/p/2/_streaming_aggregation?newDocument=true&id=search1443144481695' -d '{
"user": "dilbert",
"postDate": "2011-12-10",
"price": 60.00,
"body": "Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat" ,
"title": "Lorem ipsum"
}'
```
* Then you can call the GET request again to recive the new aggregated value...
```
curl -XGET 'http://localhost:9200/index_name/_streaming_aggregation?pretty=true&id=search1443144481695'
```
