Create a new Catalog

1. Navigate to Taxonomy > Catalogs in the main menu.
2. Click Create.
3. Enter the catalog Name.
   Catalog creation has three main sections:
4. • Included Products: to specify which products will be part of the catalog, using references to specific products, categories and other existing catalogs.
   • Excluded Products: to specify which products are not going to be part of the catalog. This specification takes precedence over the "Included Products", meaning that if a product is specified to be included and excluded at the same time, it will be excluded.
   • Category Tree: to specify the sub-tree of categories that will be accessible for the catalog users. For example to generate the main menu and navigation sidebar in the Store application.
4. in the Included Products Section
5. • Enter Include Products in Categories: The list of categories to include products from.
   • Enter Include Products in Catalogs: The list of existing catalogs to include products from.
   • Add specific products that will be included in the catalog:

       • Not selected
       • All Products
     • Use the Search text input box to find the products within the selected scope.
     • Check/Uncheck the desired products from the resultset. Products will be saved once Save button is clicked.

Indexing Process

After creating or updating a catalog, an Indexing Process will begin. The indexing process consists in determining the set of products that belong to a catalog.
Indexing Process consists in:

• Include in the partial result the union of products in all catalogs referenced in included Catalogs (with no duplication).
• Include in the partial result the union of products assigned to all categories referenced in included Categories (with no duplication).
• Include in the partial result all the products referenced in included Products.
• Exclude from the partial result the union of products in all catalogs referenced in excluded Catalogs (the resulting products that were in the partial result are removed from it).
• Exclude from the partial result the union of products assigned to all categories referenced in excluded Categories (the resulting products that were in the partial result are removed from it).
• Exclude from the partial result all the products referenced in excluded Products (the resulting products that were in the partial result are removed from it).

After a catalog is indexed, that action could potencially trigger other catalogs reindexing. The potencially affected catalogs are those that reference (directly or indirectly) the indexed catalog in includedCatalogs or excludedCatalogs fields.
