WebSphere Commerce Search extension indexes

Extension indexes, set up as index subtypes in WebSphere Commerce Search, are used to keep data in a separate core for performance reasons. The following extension indexes are available by default:

Inventory

The inventory index, a separate index that contains index data, is an extension of the product index. For accurate inventory status, we can refresh the inventory index more frequently than the product index.

Price

The price index, a separate index that contains price data. Prices are indexed by using Index Load. It can populate a large amount of data into a separate extension index faster than the Catalog Entry index can index price data.

We can use the default extension indexes, or setup our own extension index that best match the site's requirements.
