ES Test

Once the ES cluster is successfully created (refer to the operation guide for creation), you can perform a preliminary test for the availability of the cluster. Here is an example of testing via a uhost that can access ues by using the curl command.

Cluster Status Test

curl -s -XGET 'http://<host>:9200/_cluster/health?pretty'

In normal circumstances, the system returns the result:

{ "cluster_name" : "ues-qwerty", "status" : "green", "timed_out" : false, "number_of_nodes" : 3, "number_of_data_nodes" : 3, "active_primary_shards" : 1, "active_shards" : 2, "relocating_shards" : 0, "initializing_shards" : 0, "unassigned_shards" : 0, "delayed_unassigned_shards" : 0, "number_of_pending_tasks" : 0, "number_of_in_flight_fetch" : 0, "task_max_waiting_in_queue_millis" : 0, "active_shards_percent_as_number" : 100.0 }

This indicates that the cluster is in a normal operation state, and then proceed to test data entry.

Index a Document

For example, the index is “test_index”, the type is “information”, and “1” is chosen as the ID number. At this time, the request is like this:

curl -X PUT \ http://<host>:9200/test_index/information/1 \ -H 'Content-Type: application/json' \ -d '{ "name": "test_index", "age": 5, "about": "at shanghai", "interests": ["service"] }'

Successful creation returns

{"_index":"test_index","_type":"information","_id":"1","_version":1,"result":"created","_shards":{"total":2,"successful":2,"failed":0},"created":true}

Retrieve Document

curl -X GET 'http://<host>:9200/test_index/information/1'

Returns

{"_index":"test_index","_type":"information","_id":"1","_version":1,"found":true,"_source":{ "name" : "test_index", "age": 5, "about": "at shanghai", "interests": ["service"] }}

Search Document

curl -X GET 'http://<host>:9200/_search' curl -X GET 'http://<host>:9200/test_index/_search' curl -X GET 'http://<host>:9200/test_index/information/_search' curl -X GET "http://<host>:9200/_sql" -H 'Content-Type: application/json' -d'select * from test_index limit 10'

Complex search requires the use of POST method, for details please refer to the Function Document API Document.

Update Document

curl -X PUT \ http://<host>:9200/test_index/information/1 \ -H 'Content-Type: application/json' \ -d '{ "name" : "test_index", "age": 5, "about": "at shanghai", "interests": ["service", "professional"] }'

Successful update returns

{"_index":"test_index","_type":"information","_id":"1","_version":2,"result":"updated","_shards":{"total":2,"successful":2,"failed":0},"created":false}
