# Managing the Metadata Index

> Manage the Metadata Index from the Lerian Console — list, create, and remove indexed metadata keys to speed up searches across your Midaz entities.

Use the **Midaz Module** to manage the **Metadata Index**. Metadata indexes let you efficiently query entities by the custom key/value metadata you attach to organizations, ledgers, accounts, transactions, and other resources.

## What you can do

* **List indexes** to see which metadata keys have an index.
* **Create an index** on a metadata key to speed up lookups and filters on that key.
* **Remove an index** when you no longer query that metadata key.

Create an index for a supported entity and metadata key. `unique` defaults to `false`; `sparse` defaults to `true`.

Keep the index focused on the keys you actually query. This keeps search fast and predictable.
