Need Help.
I have data in elasticsearch, field "interests" like this:
{
"interests": "A,C,D,E"
},
{
"interests": "B,C,D"
},
{
"interests": "A,B,C,D,E"
},
{
"interests": "D,E"
}
I want to get data like this:
{
"key": "A",
"doc_count": 2
},
{
"key": "B",
"doc_count": 2
},
{
"key": "C",
"doc_count": 3
},
{
"key": "D",
"doc_count": 4
},
{
"key": "E",
"doc_count": 3
}
what steps should I take.
Thank you.
>Solution :
A simple terms
aggregation should do the job:
POST test/_search
{
"aggs": {
"interests": {
"terms": { "field": "interests" }
}
}
}
