Search Index JSON Properties

  • reference
    +
    Use a JSON payload to control the settings for a Search index.

    When you create a Search index with the REST API, you must give a JSON payload with the settings for the new Search index.

    Your JSON payload must contain the properties described in Initial Settings, including the Params Object.

    Initial Settings

    The start of the JSON payload for a Search index contains important settings for your index:

    {
        "name": "gfx",
        "type": "fulltext-index",
        "uuid": "28b999e9e17dd4a7",
        "sourceType": "gocbcore",
        "sourceName": "travel-sample",
        "sourceUUID": "d3604c0ec4792b4c6c5f7f2cc8207b80",
        "sourceParams": {},
        "planParams": {
            "maxPartitionsPerPIndex": 1024,
            "indexPartitions": 1,
            "numReplicas": 0
        },
        "params": {
    To view the entire JSON payload, click View.

    All Search index payloads have the following properties:

    Property Type Required? Description

    name

    String

    Yes

    The name of the Search index. A Search index name must be unique for each cluster.

    type

    String

    Yes

    The type of index you want to create:

    • fulltext-index: Create a Search index.

    • fulltext-alias: Create an alias for a Search index. For more information about Search index aliases, see Create Search Index Aliases.

    uuid

    String

    No

    The Search Service automatically generates a UUID for a Search index.

    If you use an existing UUID, the Search Service updates the existing Search index. Don’t include the uuid property when you want to copy an index to a different cluster or create a new index.

    sourceType

    String

    Yes

    The sourceType is always "gocbcore".

    sourceName

    String

    Yes

    The name of the bucket where you want to create the Search index.

    The Search Service automatically finds the UUID for the bucket.

    sourceUUID

    String

    No

    The UUID of the bucket where you want to create the Search index.

    The Search Service automatically finds the UUID for the bucket.

    Don’t include the sourceUUID property when you want to copy an index to a different cluster, or create a new index.

    sourceParams

    Object

    No

    This object contains advanced settings for index behavior.

    Don’t add content into this object unless instructed by Couchbase Support.

    planParams

    Object

    Yes

    An object that sets the Search index’s partitions and replications. For more information, see planParams Object.

    params

    Object

    Yes

    An object that sets the Search index’s type identifier, type mappings, and analyzers. For more information, see Params Object.

    planParams Object

    The planParams object sets a Search index’s partition and replication settings:

        "planParams": {
            "maxPartitionsPerPIndex": 1024,
            "indexPartitions": 1,
            "numReplicas": 0
        },
    To view the entire JSON payload, click View.

    The planParams object contains the following properties:

    Property Type Required? Description

    maxPartitionsPerPIndex

    n/a

    No

    This setting is deprecated. Use indexPartitions, instead.

    indexPartitions

    Number

    Yes

    The number of partitions to split the Search index into, across the nodes you have available in your database with the Search Service enabled. Use index partitions to increase index and query performance on large datasets.

    numReplicas

    Number

    Yes

    For high-availability, set the number of replicas the Search Service creates for the Search index.

    You can create up to three replicas for a Search index. Each replica creates a full copy of the Search index to increase high-availability. To turn off replication for the Search index, set numReplicas to 0.

    The number of replicas you can create depends on the number of nodes you have available with the Search Service enabled.

    Params Object

    • docid_prefix_delim: Use the leading characters in the documents' ID values, up to but not including a specified separator.

    • docid_regexp: Use a regular expression on the documents' ID values.

    If you want your Search index to only include documents from a specific collection, the mode value must be "scope.collection.{mode}".

    docid_prefix_delim

    String

    Yes

    If mode is docid_prefix_delim, set the separator character to use on a document’s ID value.

    For example, to filter documents based on the characters before a in their ID values, set docid_prefix_delim to .

    The fields array is located inside a {field_name} object. It contains the following properties:

    Property Type Required? Description

    docvalues

    Boolean

    Yes

    To include the value for each instance of the field in the Search index to support facets and sorting search results, set docvalues to true.

    To exclude the values for each instance of this field from the index, set docvalues to false.

    include_in_all

    Boolean

    Yes

    To allow this field to be searched without specifying the specific field’s name in the search, set include_in_all to true.

    When enabled, you can search this field through the specified default_field set in the type mapping.

    To only search this field by specifying the field name, set include_in_all to false.

    include_term_vectors

    Boolean

    Yes

    To use term vectors, store must be set to true.

    To allow the Search Service to highlight matching search terms in search results for this field, set include_term_vectors to true.

    You must also enable term vectors to use includeLocations in a Search query. For more information, see includeLocations.

    To disable term highlighting and reduce index size, set include_term_vectors to false.

    index

    Boolean

    Yes

    To include the child field in the Search index, set index to true.

    To exclude the child field from the index, set index to false.
