Description

List Indices (Cat)

Compact tabular listing of every index — health, status, docs count, disk usage, shards.

Cat Cluster Health

One-line summary of cluster health — status, node counts, shard counts.

Cat Nodes

Per-node overview — heap, CPU, load, disk, role, and cluster-manager status.

List Aliases (Cat)

Compact tabular alias listing — alias, index, filter, routing, is\_write\_index.

Get Cluster Health

Snapshot of cluster health — status (green/yellow/red), active/relocating shards, and pending tasks. The canonical conne...

Get Cluster Statistics

Aggregated statistics across the whole cluster — nodes, shards, storage, JVM heap, and OS/process metrics.

Get Cluster State

Full cluster state — routing table, metadata, node roster, and index settings. Very large payload; filter via the \`metri...

Get Cluster Settings

Return persistent, transient, and default cluster settings.

Update Cluster Settings

Set persistent or transient cluster settings. Persistent settings survive restarts; transient do not.

List Cluster Pending Tasks

Tasks queued on the cluster manager but not yet executed — useful to spot backlogs during allocation storms.

Get Saved Object

Fetch a single Dashboards saved object (dashboard, visualization, index-pattern, etc.) by type + id.

Find Saved Objects

Search and paginate Dashboards saved objects. The canonical enumeration endpoint for datasync discovery.

Create Saved Object

Create a new Dashboards saved object.

Update Saved Object

Update the attributes of an existing Dashboards saved object.

Delete Saved Object

Delete a Dashboards saved object by type + id.

Bulk Get Saved Objects

Fetch many saved objects in a single request.

Export Saved Objects

Export a set of saved objects (with dependencies) as an NDJSON bundle. Response body is raw NDJSON text (one JSON object...

Import Saved Objects

Import an NDJSON bundle of saved objects (produced by export or hand-crafted).

Index Document (Auto-ID)

Add a document to an index and let OpenSearch generate the ID.

Create Or Update Document (Explicit ID)

Index a document at a specific ID; overwrites if the ID already exists unless op\_type=create.

Get Document By ID

Fetch a single document (source + metadata) by its ID.

Check Document Exists

Existence check for a document — returns 200 if the document exists, 404 if not.

Get Document Source Only

Fetch only the \_source field of a document, without \_seq\_no / \_primary\_term / \_version metadata.

Partial Update Document

Apply a partial update to a document using the update DSL (doc merge, script, or upsert).

Delete Document

Delete a document by ID.

Bulk Index/Update/Delete (NDJSON)

Execute many index/update/delete operations in a single request. \*\*Body must be NDJSON\*\* (newline-delimited JSON), not s...

Bulk Operations Scoped To One Index

Same NDJSON bulk semantics as bulk\_operations, but scoped to a single index in the URL — operations can omit `_index` in...

Multi-Get Documents

Fetch multiple documents by ID in one round-trip, optionally across different indices.

Delete Documents By Query

Delete all documents matching a query in one call.

Update Documents By Query

Apply a script or noop update to every document matching a query.

Reindex Documents

Copy documents from a source index (or remote cluster) to a destination index; the canonical datasync migration primitiv...

Create Index

Create a new index with optional settings, mappings, and aliases.

Get Index Info

Return the settings, mappings, and aliases of one or more indices.

Check Index Exists

Existence check for an index — 200 if it exists, 404 if not.

Delete Index

Permanently delete an index and all its data.

Update Mapping

Add new fields to an index mapping. Cannot change existing field types.

Get Mapping

Return the mapping (field types) for one or more indices.

Get Index Settings

Return the settings for one or more indices (shard count, replicas, analysis, refresh interval).

Update Index Settings

Update dynamic index settings (replica count, refresh interval, allocation, etc.).

Refresh Index

Force a refresh so recently indexed documents become searchable immediately.

Flush Index

Persist in-memory transaction log to disk.

Force Merge Index

Merge index segments to reduce their count; heavy operation.

Open Index

Re-open a closed index so it becomes readable/writable.

Close Index

Close an index so it stops accepting reads/writes; frees cluster resources.

Clone Index

Copy an existing index to a new name — source must have the write-block set before calling.

Atomic Update Of Aliases

Apply multiple alias add/remove operations atomically.

Add Alias To Index

Attach a single alias to a single index (non-atomic — use update\_aliases for atomic swaps).

Delete Alias From Index

Remove an alias from an index.

Get Alias Info

Return details of a specific alias on a specific index (or across a wildcard set).

List All Aliases

Return every alias across every index (or a filtered subset).

Search Index

Full-text and structured search over one or more indices using the Query DSL.

Search Across All Indices

Same as search but without an index in the URL — required when using a Point-in-Time reference.

Multi-Search (NDJSON)

Run several searches in one round-trip; body is NDJSON with alternating header + query lines.

Count Documents Matching Query

Return the count of documents matching a query, without returning the hits themselves.

Scroll (Deep Pagination — Legacy)

Fetch the next batch of a scroll context. Discouraged for new work — use PIT + search\_after instead.

Clear Scroll Context

Release the memory held by one or more scroll contexts.

Create Point-in-Time

Freeze an index at a moment in time so subsequent searches see a consistent view.

Delete Point-in-Time

Release a PIT so its heap can be reclaimed.

List Snapshot Repositories

Return every registered snapshot repository on the cluster.

Get Snapshot Repository

Return details of a specific repository (type, settings).

Delete Snapshot Repository

Unregister a snapshot repository. Does NOT delete the snapshots themselves — files remain in the backend storage.

List Snapshots In Repository

List snapshots in the given repository — companion LIST for the create/get/delete snapshot actions.

Take Snapshot

Create a snapshot of one or more indices to the target repository.

Get Snapshot Details

Return details of one or more snapshots — status, indices, start/end times, shard counts.

Delete Snapshot

Delete a snapshot and reclaim its unique segments from the repository.

Restore Snapshot

Restore indices from a snapshot back into the cluster.

Get Task

Fetch the status of a running or completed task by task\_id.

Cancel Task

Cancel a running task by task\_id. Cancellation is cooperative — the task ends at the next check point.
