The indexing process for Commerce sites is configured through the /atg/commerce/search/ProductCatalogOutputConfig component. This component’s XML definition file is configured to create an XHTML document for each product in the product catalog.
The XML definition file used in ATG Store is an XML combination of:
the definition file included in the
DCS.Search.Indexmodulethe extensions added for custom catalogs in the
DCS.Search.CustomCatalogs.IndexmoduleCRS-specific extensions added in the
Store.Search.Indexmodule (and if you’re running the internationalized version of the store, also in theStore.EStore.International.Search.Indexmodule)
The CRS extensions add CRS-specific catalog properties to the index, and configure the index to get price values from price lists, as described in Indexing and Querying Price Data. For internationalized sites, the Store.Estore.International.Search.Index adds configuration for including content in multiple languages.
