NAME
Search::Elasticsearch::Client::6_0::Direct::Indices - A client for running index-level requests

VERSION
version 6.00

DESCRIPTION
This module provides methods to make index-level requests, such as creating and deleting indices, managing type mappings, index settings, 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
            aliases
        }
    );

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

Query string parameters:
    "error_trace",
    "human",
    "master_timeout",
    "timeout",
    "update_all_types",
    "wait_for_active_shards"

See the create index docs <http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-create-index.html> for more information.

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

Returns the aliases, settings, and mappings for the specified indices.

See the get index docs <http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-get-index.html>.

Query string parameters:
    "allow_no_indices",
    "error_trace",
    "expand_wildcards",
    "flat_settings",
    "human",
    "ignore_unavailable",

    );

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

Query string parameters:
    "allow_no_indices",
    "error_trace",
    "expand_wildcards",
    "flat_settings",
    "human",
    "ignore_unavailable",
    "include_defaults",
    "local"

See the index exists docs <http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-indices-exists.html> for more information.

  rollover()
    $response = $e->indices->rollover(
        alias     => $alias,                    # required
        new_index => $index,                    # optional
        body      => { rollover conditions }    # optional
    );

Rollover an index pointed to by "alias" if it meets rollover conditions (eg max age, max docs) to a new index name.

Query string parameters:
    "dry_run",
    "error_trace",
    "human",
    "master_timeout",
    "timeout",
    "wait_for_active_shards"

See the rollover index docs <https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-rollover-index.html> for more information.

  shrink()
    $response = $e->shrink(
        index  => $index,                           # required
        target => $target,                          # required
        body   => { mappings, settings aliases }    # optional
    );

The shrink API shrinks the shards of an index down to a single shard (or to a factor of the original shards).

Query string parameters:
    "error_trace",
    "human",
    "master_timeout",
    "timeout",
    "wait_for_active_shards"

See the shrink index docs <https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-shrink-index.html> 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",
    "error_trace",
    "expand_wildcards",
    "fielddata",
    "fields",
    "human",
    "ignore_unavailable",
    "query",
    "recycler",
    "request"

See the clear_cache docs <http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-clearcache.html> 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",
    "error_trace",
    "expand_wildcards",
    "human",
    "ignore_unavailable"

See the refresh index docs <http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-refresh.html> 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",
    "error_trace",
    "expand_wildcards",
    "force",
    "human",
    "ignore_unavailable",
    "wait_if_ongoing"

See the flush index docs <http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-flush.html> 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 <http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-synced-flush.html> for more information.

Query string parameters:
    "allow_no_indices",
    "error_trace",
    "expand_wildcards",
    "human",
    "ignore_unavailable"

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

The forcemerge() 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",
    "error_trace",
    "expand_wildcards",
    "flush",
    "human",
    "ignore_unavailable",
    "max_num_segments",
    "only_expunge_deletes",
    "wait_for_merge"

See the forcemerge docs <http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-forcemerge.html> 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",
    "error_trace",
    "expand_wildcards",
    "human",
    "ignore_unavailable"

See the upgrade docs <http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-upgrade.html> for more information.

        index => 'index' | \@indices    # optional
    );

Query string parameters:
    "allow_no_indices",

    $response = $e->indices->update_aliases(
        body => {

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

        body    => { query }
    );

The validate_query() method accepts a query in the "body" and checks whether the query is valid or not. Most useful when "explain" is set to "true", in which case it includes an execution plan in the output.

Query string parameters:
    "all_shards",
    "allow_no_indices",
    "analyze_wildcard",
    "analyzer",
    "default_operator",
    "df",
    "error_trace",
    "explain",
    "expand_wildcards",
    "ignore_unavailable",
    "lenient",
    "q",
    "rewrite"
