| The Collections screen provides some basic functionality for managing your Collections, powered by the <<collections-api.adoc#,Collections API>>. |
| |
| [NOTE] |
| ==== |
| If you are running a single node Solr instance, you will not see a Collections option in the left nav menu of the Admin UI. |
| |
| You will instead see a "Core Admin" screen that supports some comparable Core level information & manipulation via the <<coreadmin-api.adoc#,CoreAdmin API>> instead. |
| ==== |
| |
| The main display of this page provides a list of collections that exist in your cluster. Clicking on a collection name provides some basic metadata about how the collection is defined, and its current shards & replicas, with options for adding and deleting individual replicas. |
| |
| The buttons at the top of the screen let you make various collection level changes to your cluster, from add new collections or aliases to reloading or deleting a single collection. |

| |
| Replicas can be deleted by clicking the red "X" next to the replica name. |
| |
| If the shard is inactive, for example after a <<shard-management.adoc#splitshard,SPLITSHARD action>>, an option to delete the shard will appear as a red "X" next to the shard name. |
