NAME

Search::Elasticsearch::Client::0_90::Direct::Indices - A client for running index-level requests

VERSION

version 5.01

DESCRIPTION

This module provides methods to make index-level requests, such as creating and deleting indices, managing type mappings, index settings, warmers, index templates and aliases.

It does Search::Elasticsearch::Role::Client::Direct.

INDEX METHODS

create()

$result = $e->indices->create(
    index => 'my_index'             # required

    body  => {                      # optional
        index settings
        mappings
        warmers
    }
);

The create() method is used to create an index. Optionally, index settings, type mappings and index warmers can be added at the same time.

Query string parameters: master_timeout, timeout

See the create index docs for more information.

exists()

$bool = $e->indices->exists(
    index => 'index' | \@indices    # required
);

The exists() method returns 1 or the empty string to indicate whether the specified index or indices exist.

See the index exists docs for more information.

delete()

$response = $e->indices->delete(
    index => 'index' | \@indices    # required
);

The delete() method deletes the specified indices.

Query string parameters: master_timeout, timeout

See the delete index docs for more information.

close()

$response = $e->indices->close(
    index => 'index' | \@indices    # required
);

The close() method closes the specified indices, reducing resource usage but allowing them to be reopened later.

Query string parameters: master_timeout, timeout

See the close index docs for more information.

open()

$response = $e->indices->open(
    index => 'index' | \@indices    # optional
);

The open() method opens closed indices.

Query string parameters: master_timeout, timeout

See the open index docs for more information.

clear_cache()

$response = $e->indices->clear_cache(
    index => 'index' | \@indices        # optional
);

The clear_cache() method is used to clear the in-memory filter, fielddata, or id cache for the specified indices.

Query string parameters: allow_no_indices, expand_wildcards, fielddata, fields, filter, filter_cache, filter_keys, id, ignore_indices, ignore_unavailable, index, recycler

See the clear_cache docs for more information.

refresh()

$response = $e->indices->refresh(
    index => 'index' | \@indices    # optional
);

The refresh() method refreshes the specified indices (or all indices), allowing recent changes to become visible to search. This process normally happens automatically once every second by default.

Query string parameters: allow_no_indices, expand_wildcards, ignore_indices, ignore_unavailable

See the refresh index docs for more information.

flush()

$response = $e->indices->flush(
    index => 'index' | \@indices    # optional
);

The flush() method causes the specified indices (or all indices) to be written to disk with an fsync, and clears out the transaction log. This process normally happens automatically.

Query string parameters: allow_no_indices, expand_wildcards, force, full, ignore_indices, ignore_unavailable, refresh

See the flush index docs for more information.

optimize()

$response = $e->indices->optimize(
    index => 'index' | \@indices    # optional
);

The optimize() method rewrites all the data in an index into at most max_num_segments. This is a very heavy operation and should only be run with care, and only on indices that are no longer being updated.

Query string parameters: allow_no_indices, expand_wildcards, flush, ignore_indices, ignore_unavailable, max_num_segments, only_expunge_deletes, refresh, wait_for_merge

See the optimize index docs for more information.

snapshot_index()

$response = $e->indices->snapshot_index(
    index => 'index' | \@indices    # optional
);

Deprecated.

See the snapshot_index docs for more information.

MAPPING METHODS

put_mapping()

$response = $e->indices->put_mapping(
    index => 'index' | \@indices    # optional,
    type  => 'type',                # required

    body  => { mapping }            # required
)

The put_mapping() method is used to create or update a type mapping on an existing index. Mapping updates are allowed to add new fields, but not to overwrite or change existing fields.

For instance:

$response = $e->indices->put_mapping(
    index   => 'users',
    type    => 'user',
    body    => {
        user => {
            properties => {
                name => { type => 'string'  },
                age  => { type => 'integer' }
            }
        }
    }
);

$result = $e->indices->get_mapping(
    index => 'index' | \@indices    # optional,
    type  => 'type'  | \@types      # optional
);

The get_mapping() method returns the type definitions for one, more or all types in one, more or all indices.

See the get_mapping docs for more information.

get_field_mapping()

$result = $e->indices->get_field_mapping(
    index => 'index' | \@indices    # optional,
    type  => 'type'  | \@types      # optional,
    field => 'field' | \@fields     # required

    include_defaults => 0 | 1
);

The get_field_mapping() method returns the field definitions for one, more or all fields in one, more or all types and indices.

See the get_mapping docs for more information.

exists_type()

$bool = $e->indices->exists_type(
    index => 'index' | \@indices    # optional,
    type  => 'type'  | \@types      # required
);

The exists_type() method checks for the existence of all specified types in all specified indices, and returns 1 or the empty string.

Query string parameters: allow_no_indices, expand_wildcards, ignore_indices, ignore_unavailable

See the exists_type docs for more information.

delete_mapping()

$response = $e->indices->delete_mapping(
    index => 'index' | \@indices    # required,
    type  => 'type'                 # required
);

The delete_mapping() method deletes the type mappings (and all documents of that type) in all specified indices.

The update_aliases() method changes (by adding or removing) multiple index aliases atomically. For instance:

$response = $e->indices->update_aliases(
    body => {
        actions => [
            { add    => { alias => 'current', index => 'logs_2013_09' }},
            { remove => { alias => 'current', index => 'logs_2013_08' }}
        ]
    }
);

Query string parameters: master_timeout, timeout

See the update_aliases docs for more information.

get_aliases()
