来自Kibana DevTools的:

GET my_index_name/_search
{
  "query": {
    "match_all": {}
  }
}

使用python包elasticsearch-dsl的简单解决方案:

from elasticsearch_dsl import Search
from elasticsearch_dsl import connections

connections.create_connection(hosts=['localhost'])

s = Search(index="foo")
response = s.scan()

count = 0
for hit in response:
    # print(hit.to_dict())  # be careful, it will printout every hit in your index
    count += 1

print(count)

参见https://elasticsearch-dsl.readthedocs.io/en/latest/api.html#elasticsearch_dsl.Search.scan。

使用server:9200/_stats也可以获得所有别名的统计信息。就像每个别名的大小和元素数量一样，这非常有用，并提供了有用的信息

curl -XGET '{{IP/localhost}}:9200/{{Index name}}/{{type}}/_search?scroll=10m&pretty' -d '{
"query": {
"filtered": {
"query": {
"match_all": {}
}}'

要从所有索引中返回所有记录，您可以执行:

curl -XGET http://35.195.120.21:9200/_all/_search?size=50&pretty

输出:

  "took" : 866,
  "timed_out" : false,
  "_shards" : {
    "total" : 25,
    "successful" : 25,
    "failed" : 0
  },
  "hits" : {
    "total" : 512034694,
    "max_score" : 1.0,
    "hits" : [ {
      "_index" : "grafana-dash",
      "_type" : "dashboard",
      "_id" : "test",
      "_score" : 1.0,
       ...

使用Elasticsearch 7.5.1

http://${HOST}:9200/${INDEX}/_search?pretty=true&q=*:*&scroll=10m&size=5000

如果你也可以用&size=${number}来指定数组的大小

以防你不知道你的索引

http://${HOST}:9200/_cat/indices?v
