ElasticSearch-Äquivalent zu MongoDB .count()

The ElasticSearch equivalent to MongoDB’s count() is also called count. It can be used in a similar way

Wenn du eine ElasticSearch-Abfrage wie diese hast (Beispiel in Python)

es_equivalent_count.py

result = es.search(index="my_index", body={
    "query": {
        "match": {
            "my_field": "my_value"
        }
    }
})
result_docs = [hit["_source"] for hit in result["hits"]["hits"]]

result = es.search(index="my_index", body={
    "query": {
        "match": {
            "my_field": "my_value"
        }
    }
})
result_docs = [hit["_source"] for hit in result["hits"]["hits"]]

kannst du es einfach zu einer Nur-Count-Abfrage ändern, indem du search durch count ersetzt:

es_count_query.py

result = es.count(index="my_index", body={
    "query": {
        "match": {
            "my_field": "my_value"
        }
    }
})
result_count = result["count"] # z.B. 200

result = es.count(index="my_index", body={
    "query": {
        "match": {
            "my_field": "my_value"
        }
    }
})
result_count = result["count"] # z.B. 200
