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 \
      '{

          }
        },
        "sourceParams": {}
      }'  | 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

      {
        "status": {
          "total": 1,
