HCL Commerce Search extension indexes

Extension indexes, set up as index subtypes in HCL Commerce Search, are used to keep data in a separate core for performance reasons.

The following extension indexes are available by default:
The inventory index, a separate index that contains index data, is an extension of the product index. For accurate inventory status, you can refresh the inventory index more frequently than the product index.
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.

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