NAME
Search::Elasticsearch::Client::2_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",
"update_all_types"
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 # 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
<http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-get-index.html>.
Query string parameters:
"allow_no_indices",
"expand_wildcards",
"human",
"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
<http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-indices-
exists.html> 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
<http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-delete-index.html>
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
<http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-open-close.html>
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
<http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-open-close.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",
"expand_wildcards",
"fielddata",
"fields",
"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",
"expand_wildcards",
"force",
"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",
"expand_wildcards",
"force",
"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",
"expand_wildcards",
"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",
"expand_wildcards",
"flush",
"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.

$response = $e->indices->optimize(
index => 'index' | \@indices # optional
);
The "optimize()" method rewrites all the data in an index into at most "max_num_segments".
