# Index Type

The **Index Type** interface provides a drop-down menu from which the appropriate index type can be selected:

Following options are available:

* **Version 5.0 (Moss)** is the standard form of index to be used in test, development, and production. This version is deprecated.
* **Version 6.0 (Scorch)** reduces the size of the index-footprint on disk and provides enhanced performance for indexing and mutation-handling

> [!NOTE]
> The type of an index is saved in its JSON definition, which can be previewed in the _Index Definition Preview panel_, at the right-hand side.
