NAME

Search::Elasticsearch::Client::1_0::Direct::Indices - A client for running index-level requests

VERSION

version 6.81

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.

get()

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

Returns the aliases, settings, mappings, and warmers for the specified indices. The feature parameter can be set to none or more of: _settings, _mappings, _warmers and _aliases.

See the get index docs.

Query string parameters: allow_no_indices, expand_wildcards, ignore_unavailable, local

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.

Query string parameters: allow_no_indices, expand_wildcards, ignore_unavailable, local

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: allow_no_indices, expand_wildcards, ignore_unavailable, 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: allow_no_indices, expand_wildcards, ignore_unavailable master_timeout, timeout

See the close index docs for more information.

open()

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

The open() method opens closed indices.

Query string parameters: allow_no_indices, expand_wildcards, ignore_unavailable 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, id_cache, ignore_unavailable, query_cache, 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, force, 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_unavailable, wait_if_ongoing

See the flush index docs for more information.

flush_synced()

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

The flush_synced() method does a synchronised flush() on the primaries and replicas of all the specified indices. In other words, after flushing it tries to write a sync_id on the primaries and replicas to mark them as containing the same documents. During recovery, if a replica has the same sync_id as the primary, then it doesn't need to check whether the segment files on primary and replica are the same, and it can move on directly to just replaying the translog. This can greatly speed up recovery.

Synced flushes happens automatically in the background on indices that have not received any writes for a while, but the flush_synced() method can be used to trigger this process manually, eg before shutting down. Any new commits immediately break the sync.

See the flush synced 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_unavailable, max_num_segments, only_expunge_deletes, wait_for_merge

See the optimize index docs for more information.

get_upgrade()

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

The get_upgrade() method returns information about which indices need to be upgraded, which can be done with the upgrade() method.

Query string parameters: allow_no_indices, expand_wildcards, human, ignore_unavailable

See the upgrade docs for more information.

upgrade()

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

The upgrade() method upgrades all segments in the specified indices to the latest format.

Query string parameters: allow_no_indices, expand_wildcards, ignore_unavailable, only_ancient_segments, wait_for_completion

See the upgrade docs for more information.

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 => {

    body => {
        actions => [
            { add    => { alias => 'current', index => 'logs_2013_09' }},
            { remove => { alias => 'current', index => 'logs_2013_08' }}

The stats() method returns statistical information about one, more or all indices. By default it returns all metrics, but you can limit which metrics are returned by specifying the metric.

Allowed metrics are: _all, completion docs, fielddata, filter_cache, flush, get, id_cache, indexing, merge, percolate, query_cache, refresh, search, segments, store, warmer
