I am starting out with Elastic Search, and am stuck at trying to do some aggregation. Basically, I have a data set consisting of data in the following form:
{ "name": "The Chef Restaurant", "city": "New York", "state": "New York", "rating": "GOOD", "type": "Continental" } Now, I want to do some aggregation and get all the Continental restaurants, Good restaurants, Restaurants in New York in one query.
Note that I don't want the count of all types of restaurants, I just want the count of the specific types. Also, these aggregations are mutually independent. That is, when I say GOOD, I don't necessarily want it to be Continental, it can be Italian or anything else.
This is what I have tried:
{ "size": 0, "query": { "match_all": {} }, "aggregations": { "good_restaurants": { "filters": { "match": { "rating": "CONTINENTAL" } } }, "continental_restaurants": { "filters": { "match": { "type": "CONTINENTAL" } } }, "restaurants_in_new_york": { "filters": { "match": { "type": "CONTINENTAL" } } } } } which gives me the error:
{ "error": { "root_cause": [ { "type": "search_parse_exception", "reason": "Unknown key for a START_OBJECT in [good_restaurants]: [match].", "line": 9, "col": 17 } ], "type": "search_phase_execution_exception", "reason": "all shards failed", "phase": "query", "grouped": true, "failed_shards": [ { "shard": 0, "index": "test_master", "node": "-aWy78_mRaaBMcOAeiN9tg", "reason": { "type": "search_parse_exception", "reason": "Unknown key for a START_OBJECT in [good_restaurants]: [match].", "line": 9, "col": 17 } } ] }, "status": 400 } I know this seems like a simple question, but I have been stuck at it for a long time. Any help will be appreciated.
