Index Creation with REST API

      +

      The REST API can be used to create indexes. Each call requires the following:

      • An appropriate username and password.

      • Use of the verb PUT.

      • An endpoint referring to the Full Text Search service, on port 8094; and including the appropriate endpoint for index creation as defined by the Full Text Search REST API, including the name of the new index.

      • Headers to specify settings for cache-control (no-cache) and application-type (application/json).

      • A body containing the JSON document that defines the index to be created. This must include the name of the bucket on which the index is to be created.

      The simplest way to create the appropriate JSON index-definition for the body is to create an index by means of the Couchbase Web Console, make a copy of the JSON index-definition produced (by accessing the Using the Index Definition Preview, explained above), modify the index-definition as appropriate, and finally, add the index-definition to the other, preceding elements required for the call.

      Note, however, that this requires modification of the uuid field; since the re-specifying of an existing field-value is interpreted as an attempted update, to an existing index. Therefore, if the uuid field for an existing index appears in the Index Definition Preview as "uuid": "3402702ff3c862c0", it should be edited to appear "uuid": "". A new ID will be allocated to the new index, and this ID will appear in the Index Definition Preview for the new index.

      Note also that a similar condition applies to the sourceUUID field, which refers to the targeted bucket: if a new index is being created for the same bucket that was referred to in the index-object copied from the UI, the field-value can remain the same. However, if a different bucket is now to be targeted, the field should be edited to appear "sourceUUID": ""

      When specifying the endpoint for the index you are creating, make sure the path-element that concludes the endpoint is the same as that specified in the name field (which is the first field in the object).

      The following curl example demonstrates the creation of an index named demoIndex, on the inventory scope and airline collection, within the travel-sample bucket. It assumes that Couchbase Server is running on localhost, and that the required username and password are Administrator and password.

      Example

      curl -XPUT -H "Content-Type: application/json" \
      -u <username>:<password> http://localhost:8094/api/index/demoIndex -d \
      '{
        "type": "fulltext-index",
        "name": "demoIndex",
        "uuid": "4b70593a69cfcd79",
        "sourceType": "gocbcore",
        "sourceName": "travel-sample",
        "sourceUUID": "fc9b8eec20f8f7713ad14498064f50aa",
        "planParams": {
          "maxPartitionsPerPIndex": 1024,
          "indexPartitions": 1
        },
        "params": {
          "doc_config": {
            "docid_prefix_delim": "",
            "docid_regexp": "",
            "mode": "scope.collection.type_field",
            "type_field": "type"
          },
          "mapping": {
            "analysis": {},
            "default_analyzer": "standard",
            "default_datetime_parser": "dateTimeOptional",
            "default_field": "_all",
            "default_mapping": {
              "dynamic": true,
              "enabled": false
            },
            "default_type": "_default",
            "docvalues_dynamic": false,
            "index_dynamic": true,
            "store_dynamic": false,
            "type_field": "_type",
            "types": {
              "inventory.airline": {
                "dynamic": true,
                "enabled": true
              }
            }
          },
          "store": {
            "indexType": "scorch",
            "segmentVersion": 15
          }
        },
        "sourceParams": {}
      }'

      If the call is successful, the following object is returned:

      {"status":"ok"}

      The newly created index can then be inspected in the Couchbase Web Console.

      Index Update with REST API

      Specifying the "uuid" parameter in the index definition is required for the index creation to be treated as a valid update.

      This uuid in the JSON body of a valid index update request has to match that of the existing index definition. Upon successful creation/update of an index, the uuid will be re-initialized.
