  - Persistent object model
    HCL Commerce deals with a large amount of persistent data. There are numerous tables defined in the current database schema. Even with this extensive schema, however, you might need to extend or customize the database schema for your particular business needs.
  - Creating your custom store
    After you install and set up your programming environment, you can create your custom store and customize your storefront. You must ensure that the store server is properly configured, and that your store assets are moved to the Store server.
  - Presentation layer
    HCL Commerce uses Java Server Pages (JSP) to implement the view layer of the Model-View-Controller (MVC) design pattern. The view layer is in charge of retrieving data from the database through the use of data beans and formatting it to meet the display requirements. The view layers determines whether the request is sent to a browser or streamed out as XML. JSP files present a clean separation between data content and presentation.
  - Controller layer
    The Controller layer is the conductor of operations for a request. It controls the transaction scope and manages the session related information for the request. The controller first dispatches to a command and then calls the appropriate view processing logic to render the response.
  - Business logic layer
    The business logic layer is the business components that provide OAGIS services to return data or start business processes. The presentation layer uses these OAGIS services to display data, or to invoke a business process. The business logic provides data required by the presentation layer. The business logic layer exists because more than just fetching and updating data is required by an application; there is also additional business logic independent of the presentation layer.
  - Persistence layer
    The interaction between the business objects and persistence layer is isolated in an object called the Business Object Mediator. Business object document (BOD) commands interact with the Business Object Mediator to handle the interaction with the logical objects and how they are persisted.
  - Business model information model
    A business model, a representation of the business processes used throughout the site, provides a sample commerce solution which includes an organization structure, default user roles and access control policies, one or more starter stores, administration tools, and business processes that demonstrate best practices. A business model can be customized to support business requirements and scenarios. HCL Commerce provides sample business models that show some common commerce solutions. These business models are created by setting up an organization hierarchy structure, access control policies, stores, and contracts that help satisfy the necessary business requirements.
  - Business models
    Before starting to develop your site with HCL Commerce, you need to determine the business model supported by HCL Commerce that best represents the purpose of your site. Usually sites created with HCL Commerce will be implemented based on of one of these business models.
  - Store data information model
    Store data is the information that is loaded into the Transaction server database, which allows your store to function. The URL Registry Entries and View Registry Entries packages are included in the diagram, but they are not database assets. These entries are presentation configuration (that is, struts actions and forwards) that must be deployed. URL registry entries are shown in the diagram to illustrate the entire store data information model. To operate properly, a store must have the data in place to support all customer activities. For example, in order for a customer to make a purchase, your store must contain a catalog of goods for sale (catalog data), the data associated with processing orders (tax and shipping data), and the inventory to fulfill the request (inventory and fulfillment data).
  - Customizing HCL Commerce
    You can extend the HCL Commerce product to fit your business needs. This topic describes the prerequisite skills and required knowledge that you need to customize business logic.

If you are migrating from a previous version of the product, there are mandatory and optional areas to work with, depending on your existing customizations. In the following topics the available customization points are described, and you are given detailed instructions on customizing each.
        Customizing the index life cycle
        The HCL Commerce Search index life cycle provides numerous extension points. There are eight main stages to the life cycle, and each of these comes with its own extension opportunities. Your primary tool for customization is the configuration files that control the indexing process. Beyond configuration, you can build and integrate your own custom code.
        Search index schema customization file x-schema.xml
        Adding new fields into the index schema requires modifying the x-schema.xml file to add the new index field. Typically, an existing index is updated to add new fields (local index). In other instances, it is recommended to extend the product index by creating an index as an extension of an existing index (extension index).
        Extending the base index schema
        The base index schema can be extended to suit your business needs. For example, to separate data into different indexes that are based on their refresh intervals.
        Setting up the search index
        The Search index is set up automatically during Search server startup. Search cores are created according to the configuration settings defined in the SRCHCONF and SRCHCONFEXT database tables. You can customize these tables to control the creation of search index cores.
        Customizing indexing
        The indexing process requires mapping data from an external source (database or file) to index fields to create index records or index documents. Depending on the complexity of the source data and index schema design, preprocessing the data might be required. Otherwise, indexing can be directly performed by using either the Data Import Handler (DIH) to index data from the database, or Solr APIs to index data from a file.
        Customizing the search run time
        You can customize several areas of the search run time.
        Adding custom index fields in REST responses
        You can add custom index fields to be returned in REST responses by updating the wc-component.xml file.
        Customizing search profiles
        HCL Commerce Search uses search profiles to control the storefront search experience at a page-level. Search profiles group search runtime parameters (search index name, search index fields, expression providers and result filters, paging and sorting), and search feature configurations (text highlight, facets, and spelling correction). Search profiles are defined in the HCL Commerce Search configuration file, wc-search.xml.
        Customizing HCL Commerce Search in the Management Center
        You must customize HCL Commerce Search when you are adding new indexed catalog entry properties to search rule actions or targets.
        Adding catalog entry properties to search rule actions or targets
        Search rule actions and targets in the Management Center dynamically populate a list of catalog entry indexed properties. You must customize HCL Commerce search when you are adding new indexed catalog entry properties to search rule actions or targets.
        Migrating catalog entry properties to search rule actions or targets
        Search rule actions and targets in the Management Center are enhanced to dynamically populate a list of catalog entry indexed properties. You must customize HCL Commerce Search when you are working with existing migrated search rule actions or targets.
        Customizing HCL Commerce Search in the storefront
        You can customize HCL Commerce Search in the storefront to suit your business needs. You can customize HCL Commerce Search according to your role within the WebSphere Commerce site.
        Category navigation rules
        You can use navigation rules to sort products in a category via a specific criterion such as price.
        Customizable components of the final Solr query
        You can customize components of the final Solr query by using query parsers. A query parser is a component responsible for parsing the textual query and converting it into corresponding Lucene Query objects.
        Search term association handling
        Search term associations are used to suggest more, different, or replacement products in search results. Search term associations can also link search terms to a selected landing page in the store. Business users create and manage search term associations in the Management Center by using the Catalogs tool.
        Limitations of HCL Commerce Search
