Write efficient data queries in B2C Commerce for products, customers, and orders. Use this skill whenever the user needs to search products on a storefront page, look up customer profiles, query orders, paginate search results, or fix slow category pages. Also use when they ask about performance problems with data access, replacing database-intensive APIs with index-backed alternatives, or choosing between search vs query methods — even if they just say "my category page is slow" or "how do I find customers by email".

Querying Data in B2C Commerce
Efficient data querying is critical for storefront performance and job stability. B2C Commerce provides index-backed search APIs and database query APIs—choosing the right one for each use case avoids performance problems.
Product Search (Storefront)
Use ProductSearchModel for all storefront product searches. It is index-backed and designed for high-traffic pages.
Basic Product Search
varProductSearchModel = require('dw/catalog/ProductSearchModel');
var psm = newProductSearchModel();
psm.setCategoryID('electronics');
psm.setOrderableProductsOnly(true); // Only in-stock products
psm.setSearchPhrase('laptop');
psm.search();
var hits = psm.getProductSearchHits();
while (hits.()) {
hit = hits.();
productID = hit.;
minPrice = hit.;
maxPrice = hit.;
}
hits.();
hasNext
var
next
var
productID
var
minPrice
var
maxPrice
close
Paging Search Results
Always page results—never load the full result set:
varProductSearchModel = require('dw/catalog/ProductSearchModel');
varPagingModel = require('dw/web/PagingModel');
var psm = newProductSearchModel();
psm.setCategoryID('mens-clothing');
psm.setOrderableProductsOnly(true);
psm.search();
var pagingModel = newPagingModel(psm.getProductSearchHits(), psm.count);
pagingModel.setPageSize(12);
pagingModel.setStart(0); // page offsetvar pageElements = pagingModel.pageElements;
while (pageElements.hasNext()) {
var hit = pageElements.next();
// Render product tile
}
Getting Variation Data from Search Hits
Use ProductSearchHit methods instead of loading full product objects:
// GOOD: Get variation info from the search hit (index-backed)var representedColors = hit.getRepresentedVariationValues('color');
var representedIDs = hit.getRepresentedProductIDs();
var minPrice = hit.getMinPrice();
var maxPrice = hit.getMaxPrice();
// BAD: Loading the full product and iterating variants (database-intensive)var product = hit.product;
var variants = product.getVariants(); // Expensive!var priceModel = product.getPriceModel(); // Expensive!
Search Refinements
var psm = newProductSearchModel();
psm.setCategoryID('shoes');
psm.addRefinementValues('color', 'blue');
psm.addRefinementValues('size', '10');
psm.setPriceMin(50);
psm.setPriceMax(200);
psm.search();
// Get available refinement values for the current result setvar refinements = psm.getRefinements();
var colorValues = refinements.getAllRefinementValues('color');

Order Queries
OrderMgr.searchOrders / queryOrders
Use searchOrders for index-backed order lookups and queryOrders for database queries:
varOrderMgr = require('dw/order/OrderMgr');
varOrder = require('dw/order/Order');
// Index-backed search (preferred for common lookups)var orders = OrderMgr.searchOrders(
'customerEmail = {0} AND status != {1}',
'creationDate desc',
'customer@example.com',
Order.ORDER_STATUS_FAILED
);
while (orders.hasNext()) {
var order = orders.next();
// Process order
}
orders.close(); // Always close iterators
Query by Date Range
varOrderMgr = require('dw/order/OrderMgr');
varCalendar = require('dw/util/Calendar');
varOrder = require('dw/order/Order');
var startDate = newCalendar();
startDate.add(Calendar.DAY_OF_YEAR, -7);
var orders = OrderMgr.searchOrders(
'creationDate >= {0} AND status = {1}',
'creationDate desc',
startDate.time,
Order.ORDER_STATUS_NEW
);
while (orders.hasNext()) {
var order = orders.next();
// Process
}
orders.close();
Prefer searchOrders for storefront and high-traffic code paths. Use queryOrders only when you need to query attributes not available in the search index.
Customer / Profile Queries
CustomerMgr (Preferred)
Use searchProfiles for index-backed searches and processProfiles for batch processing in jobs:
varCustomerMgr = require('dw/customer/CustomerMgr');
// Index-backed search (storefront use)var profiles = CustomerMgr.searchProfiles(
'email = {0}',
'lastLoginTime desc',
'customer@example.com'
);
while (profiles.hasNext()) {
var profile = profiles.next();
// Process profile
}
profiles.close();
Batch Processing (Jobs)
Use processProfiles for jobs that need to iterate over many profiles—it has optimized memory management:
varCustomerMgr = require('dw/customer/CustomerMgr');
functionprocessProfile(profile) {
// Process each profile individually// Memory is managed automatically
}
// Process all profiles matching the queryCustomerMgr.processProfiles('gender = {0}', processProfile, 1);
Important:processProfiles replaces the older queryProfiles and SystemObjectMgr.querySystemObjects for customer data. It uses the full-text search service with better performance and memory characteristics.
Customer Query Behaviors
Wildcards (*, %, +) are filtered from queries and replaced by spaces
LIKE and ILIKE execute as full-text queries (match whole words, not substrings)
LIKE is case-insensitive
Combining AND and OR in the same query degrades performance
Range queries (e.g., a > b) impact performance
Results are limited to the first 1000 hits
System Object Queries (SystemObjectMgr)
For querying system objects other than customers (e.g., SitePreferences, catalogs):
varSystemObjectMgr = require('dw/object/SystemObjectMgr');
// Query system objectsvar results = SystemObjectMgr.querySystemObjects(
'Profile',
'custom.loyaltyTier = {0}',
'lastLoginTime desc',
'Gold'
);
while (results.hasNext()) {
var obj = results.next();
// Process
}
results.close();
Note: For customer profiles specifically, prefer CustomerMgr.searchProfiles or CustomerMgr.processProfiles over SystemObjectMgr.querySystemObjects—they use the search index and perform significantly better.
Database-Intensive APIs to Avoid
These APIs hit the database directly and are expensive on high-traffic pages. Replace them with index-friendly alternatives. See Performance-Critical APIs for the complete list with impact details.
Avoid (Database-Intensive)
Use Instead (Index-Friendly)
Category.getProducts() / getOnlineProducts()
ProductSearchModel.setCategoryID()
ProductMgr.queryAllSiteProducts()
ProductSearchModel.search()
Product.getVariants() / getVariationModel()
ProductSearchHit methods
Product.getPriceModel() (in loops)
ProductSearchHit.getMinPrice() / getMaxPrice()
CustomerMgr.queryProfiles()
CustomerMgr.searchProfiles() or processProfiles()
