Creating a Dynamic Index via the REST API
This example quickly creates the same index as Creating a Dynamic Index via the UI.
The cURL command below was initially created via the Classic Editor in the UI, however the follwoing modifications were made.
- 
The curl flag "-s" to suppress some runtime output.
 - 
The credentials "-u <username>:<password>" were altered to "-u ${CB_USERNAME}:${CB_PASSWORD}".
 - 
The hostname or IP address was replaced with ${CB_HOSTNAME}.
 - 
The commands output is piped through the utility jq to enhance readability.
 - 
The two (2) UUIDs were removed (similar to the below) because we want to make a new index not modify an existing one.
"uuid": "273a60635f5248e5", "sourceUUID": "2b421d183cb76aebbffa45424736ec2e", 
The Creation Command
The full command to create the index is below and can be executed verbatim if you have the environment variable ${CB_USERNAME}, ${CB_PASSWORD} and ${CB_HOSTNAME} set.
curl -s -XPUT -H "Content-Type: application/json" \
-u ${CB_USERNAME}:${CB_PASSWORD} http://${CB_HOSTNAME}:8094/api/index/test_dynamic -d \

}'  | jq .
If you successfully create the index you should a response liekt the follwoing
{
  "status": "ok",
  "uuid": "56304e8bab69bc99"
}
Test the Dynamic Index with a simple query
Request the first 10 item closet to a longitude of -2.235143 and a latitude of 53.482358.
The target-field geo is specified, as is a distance of 100 miles: this is the radius within which target-locations must reside for their documents to be returned.  Don’t worry about newlines when you paste the text.
curl -s -XPOST -H "Content-Type: application/json" \
-u ${CB_USERNAME}:${CB_PASSWORD} http://${CB_HOSTNAME}:8094/api/index/test_dynamic/query \
-d '{
  "query": {
    "query": "+view +food +beach"
  },
  "size": 10,
  "from": 0
}' |  jq .
The output of a ten (10) hits (from a total of 121 matching docs) is as follows
