For indexing, commerce catalogs are typically broken down by product. Each product item is transformed into an XHTML document based on a definition file. The definition file specifies that each output document should include information about the product’s parent category and child SKUs (as well as the product itself), so that site visitors can search category or SKU properties in addition to product properties.
The DCS.Search module includes an IndexingOutputConfig component and definition file that are preconfigured to work with a typical catalog repository. You can use this component and definition file as is, or modify them or create your own component based on them. The component, /atg/commerce/search/ProductCatalogOutputConfig, is configured like this:
definitionFile=/atg/commerce/search/product-catalog-output-config.xml bulkLoader=/atg/search/repository/BulkLoader incrementalLoader=/atg/search/repository/IncrementalLoader enableIncrementalLoading=false variantProducers=LocaleVariantProducer indexingSynchronizations+=\ /atg/commerce/search/refinement/RefinementConfigurationSubmitter
The XML definition file, product-catalog-output-config.xml, is designed to output the catalog properties that users are most likely to search for, and exclude the least likely ones. For example, it includes the product’s display name and description properties and the list price and sale price of the child SKUs, but omits all image properties.
The following is a sample XHTML file generated for a product, based on the product-catalog-output-config.xml definition file:
