Key Takeaways
- Magento’s default search engine is Elasticsearch/OpenSearch — product search extensions improve on this foundation with autocomplete, synonym management, faceted navigation, and AI-powered result relevance.
- Stores with AI search report 22–41% higher conversion rates compared to default catalog search — making search quality one of the highest-leverage ecommerce optimizations available.
- Adobe Live Search replaces Magento’s default search with an AI-powered SaaS service that understands natural language, auto-corrects typos, and re-ranks results based on shopper behavior — included free with Adobe Commerce licenses.
- Top third-party extensions for Magento Open Source include Mirasvit ($249 one-time), Amasty ($269–$499 tiered), MageArmy ($99 flat), and SaaS solutions Algolia and Klevu/Athos Commerce billed monthly.
- Yes, Magento is now Adobe — Adobe acquired Magento in 2018, and the enterprise version is now Adobe Commerce, while the open-source community version remains Magento Open Source.
What Is a Magento Extension?
A Magento extension is a modular software package that adds, modifies, or extends functionality in a Magento or Adobe Commerce store — installed through the Adobe Commerce Marketplace or directly via Composer, the PHP dependency manager. Extensions are the primary mechanism through which Magento’s functionality is customized beyond its core feature set, covering everything from payment gateways and shipping integrations to product search, loyalty programs, and custom checkout flows.
Magento’s architecture is specifically designed to support modular extension development — extensions can override core classes, add new admin panels, inject custom logic into the checkout process, or replace entire subsystems (like the search engine) with alternative implementations without modifying core files. This architecture means extensions survive core platform updates without losing their customizations, though compatibility with each new Magento/Adobe Commerce release must be confirmed for each extension.
For product search specifically, extensions either extend Magento’s built-in Elasticsearch/OpenSearch foundation with additional features (autocomplete, synonyms, merchandising rules) or replace the search layer entirely with a hosted SaaS search engine.
Is Magento Now Adobe?
Yes. Adobe acquired Magento in May 2018 for approximately $1.68 billion. The platform now exists in two forms:
Adobe Commerce — the enterprise version, available both as a cloud-hosted SaaS (Adobe Commerce on Cloud, formerly Magento Commerce Cloud) and as an on-premises installation. Adobe Commerce includes Live Search, Product Recommendations powered by Adobe Sensei AI, and a growing suite of native services not available in the open-source edition.
Magento Open Source — the community-maintained open-source version, formerly Magento Community Edition. Still actively developed, still free to download and deploy, but without the enterprise services bundled in Adobe Commerce. Open Source merchants access equivalent functionality through third-party extensions from the Adobe Commerce Marketplace and other sources.
Magento 2.4.8 requires OpenSearch 2.19 or Elasticsearch 8.17 as the search engine foundation, regardless of which edition is running. Both editions use the same core search architecture; they differ in which native services are available on top of it.
What Is Elasticsearch in Magento 2?
Default Magento search uses OpenSearch or Elasticsearch to match keywords in product attributes. Elasticsearch (and its AWS-maintained fork OpenSearch, which Magento now supports interchangeably) is a distributed search engine that indexes product data — names, descriptions, attributes, SKUs, and custom fields — and returns results based on relevance scoring rather than simple database queries.
The Magento/Elasticsearch integration provides several capabilities over a pure database query approach:
Full-text relevance ranking — results are ranked by relevance score rather than database sort order, meaning a search for “waterproof hiking boot” returns the most relevant products rather than just products containing those exact words.
Attribute weighting — product name matches can be weighted higher than description matches, so a product whose name contains the search term ranks above one where the term only appears in a long description.
Faceted navigation — layered navigation filtering (brand, price range, size, color) is powered by Elasticsearch aggregations, enabling fast, real-time filter counts without expensive database queries.
Scalability — Elasticsearch handles catalogs from hundreds to millions of SKUs without the search speed degradation that pure database approaches exhibit at scale.
The Elasticsearch extension returns relevant results within milliseconds, across products, categories, CMS pages, and 15+ other content types — powering search for thousands of Magento stores, from catalogs of a hundred products to millions of SKUs.
The limitation of default Magento’s Elasticsearch implementation is that it’s relatively basic in its configuration — it works but lacks the merchandising rules, synonym management, AI reranking, and behavioral personalization that conversion-optimized search requires. This gap is where product search extensions provide their value.
Top Magento Product Search Extensions in 2026
Adobe Commerce Live Search (Native — Adobe Commerce only)
Adobe Live Search replaces Magento’s default Elasticsearch-based search with a Sensei-powered engine. Live Search provides synonym management, merchandising rules, boosting and burying, faceted navigation, and query autocomplete. The AI layer learns from search behavior to improve result relevance — a significant improvement over default Magento search for catalogs with more than a few hundred SKUs. Included free with Adobe Commerce licenses; not available for Magento Open Source.
Mirasvit Elasticsearch Extension ($249 one-time)
The full relevance and autocomplete toolkit in a single $249 edition, self-hosted on your own Elasticsearch or OpenSearch. Features include search weights, score-boost rules, singular/plural handling, stemming, and wildcards. Approved and published on the Adobe Commerce Marketplace, meeting Adobe’s quality and security standards. Best for mid-to-large catalogs on Magento Open Source or Adobe Commerce on-premises where full control over search infrastructure is required.
Amasty Advanced Search and Elastic Search ($269–$499)
Amasty offers a three-tier ladder: $269 Advanced, $329 Elastic, and $499 Premium for the brand layer and AI content generator. Amasty Elastic Search offers fast and relevant search results, leveraging Elasticsearch to provide blazing-fast, precise search results alongside synonym support, spell correction, and search analytics.
MageArmy Elasticsearch Autocomplete ($99 flat)
For small and medium-sized Magento merchants, MageArmy Elasticsearch Autocomplete & Product Suggestion is recommended as the top choice. It offers weight-based relevance, SKU search, and synonym support at a highly competitive flat price of $99 for both Open Source and Adobe Commerce — this uniform pricing model makes it an outstanding value proposition.
Algolia for Magento (SaaS, monthly pricing)
Algolia is a fully hosted SaaS search billed monthly or by usage. Product data is pushed to Algolia’s external service at index time, and every query is answered by their service — very fast, with no load on Magento — but because results are drawn outside Magento, they are harder to fit to your storefront’s look and logic. Best for high-traffic stores where search speed is a primary concern and the off-server SaaS architecture is acceptable.
Klevu / Athos Commerce (SaaS, monthly pricing)
Klevu and Searchspring merged into Athos Commerce in January 2025. Both products continue under the Athos Commerce umbrella. A strong enterprise SaaS option with advanced AI merchandising and behavioral personalization.
ElasticSuite by Smile (Free, open-source)
A free, developer-oriented Elasticsearch extension with solid core functionality — a strong starting point for budget-conscious merchants with development resources to configure it.
Self-Hosted vs SaaS Search Extensions: The Core Decision
Native Magento search and Smile ElasticSuite cost nothing (basic/developer-oriented); Algolia and Klevu are fully hosted search on ongoing subscriptions. The three paid extensions all run on Elasticsearch or OpenSearch and overlap on the basics — instant autocomplete, SKU search, and add-to-cart.
The decision between self-hosted (Mirasvit, Amasty, MageArmy) and SaaS (Algolia, Klevu/Athos) maps cleanly to priorities:
Choose self-hosted when: Full control over result logic and appearance matters, per-query fees are unacceptable at your traffic volume, or your Magento server infrastructure is already robust enough to handle search load.
Choose SaaS when: Search speed at scale is the primary concern, you want managed infrastructure, and the per-query cost model is acceptable relative to the engineering cost of maintaining self-hosted search.
How to Check if Product Is in Stock in Magento 2
Stock status checking in Magento 2 can be done through several approaches depending on whether you’re working in PHP code, the admin panel, or the frontend:
In the Admin Panel:
Navigate to Catalog → Products → find the product → scroll to the Quantity section. The In Stock/Out of Stock status is displayed alongside the quantity figure. Bulk stock status can be viewed in the product grid by adding the Quantity column via the Columns selector.
In PHP/Code (using Object Manager for quick checks):
php
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$stockItem = $objectManager->get(‘\Magento\CatalogInventory\Api\StockRegistryInterface’);
$stock = $stockItem->getStockItem($productId);
$isInStock = $stock->getIsInStock();
Note: Direct Object Manager usage is not recommended for production code — dependency injection via constructors is the proper Magento development approach.
Via StockStateInterface (recommended production approach):
php
public function __construct(
\Magento\CatalogInventory\Api\StockStateInterface $stockState
) {
$this->stockState = $stockState;
}
$isInStock = $this->stockState->verifyStock($productId);
How to Get Product Stock Status in Magento 2
For more complete stock status information including quantity and availability, the StockRegistryInterface provides the most comprehensive data:
php
use Magento\CatalogInventory\Api\StockRegistryInterface;
class YourClass
{
private StockRegistryInterface $stockRegistry;
public function __construct(StockRegistryInterface $stockRegistry)
{
$this->stockRegistry = $stockRegistry;
}
public function getStockStatus(int $productId): array
{
$stockItem = $this->stockRegistry->getStockItem($productId);
return [
‘qty’ => $stockItem->getQty(),
‘is_in_stock’ => $stockItem->getIsInStock(),
‘manage_stock’ => $stockItem->getManageStock(),
‘backorders’ => $stockItem->getBackorders(),
];
}
}
For MSI (Multi-Source Inventory, introduced in Magento 2.3+) environments where multiple inventory sources are configured, use the GetProductSalableQty service instead:
php
use Magento\InventorySalesAdminUi\Model\GetSalableQuantityDataBySku;
// Get salable quantity across all sources for default stock
$salableQty = $this->getSalableQuantityDataBySku->execute($sku);
Via the REST API:
GET /rest/V1/stockItems/{productSku}
Returns full stock item data including quantity, stock status, and inventory management settings.
How to Choose the Right Magento Product Search Extension
Start with your edition. Adobe Commerce merchants should evaluate Live Search first — it’s included in the license and significantly better than default search for most catalog sizes.
Assess your catalog size and complexity. For large enterprise merchants with complex search requirements, multi-store setups, or a need for deep analytics and reporting, Mirasvit and Amasty are the preferred choices.
Consider infrastructure ownership. If your hosting environment already has a well-configured Elasticsearch cluster, self-hosted extensions like Mirasvit or Amasty maximize that investment. If search infrastructure management is a burden you’d rather not carry, SaaS options remove that overhead.
Evaluate Hyvä compatibility if relevant. MageArmy’s extension is specifically recommended for Hyvä theme compatibility — Hyvä-based stores have fewer compatible extensions than Luma-based stores, making compatibility a meaningful filter.
Common Mistakes When Implementing Magento Product Search Extensions
- Installing an extension without auditing existing search queries first — Google Search Console and Magento’s native search term report both reveal what customers are searching for and where current search fails; this data should inform extension configuration before deployment.
- Skipping synonym configuration — industry jargon, product-specific abbreviations, and common customer misspellings all need to be mapped in the synonym dictionary before search quality genuinely improves.
- Choosing a SaaS extension without calculating total cost of ownership — monthly per-query pricing at high traffic volumes can exceed the one-time license cost of self-hosted alternatives within months.
- Not testing search on mobile specifically — autocomplete behavior, result panel sizing, and keyboard interactions are materially different on mobile and require dedicated QA regardless of desktop search performance.
- Ignoring MSI compatibility for multi-source inventory setups — extensions built before MSI (pre-Magento 2.3) may not correctly reflect stock status across multiple warehouse sources without additional configuration.
Wrapping Up
The right Magento product search extension depends on three things — your Magento edition (Adobe Commerce or Open Source), your catalog size and complexity, and whether you want infrastructure ownership or managed SaaS convenience. Adobe Commerce merchants should start with Live Search before evaluating third-party options; Open Source merchants have strong choices at every price point from free (ElasticSuite) to enterprise SaaS (Algolia, Athos Commerce). The conversion rate improvement from better search is among the most consistently documented ecommerce optimization available, making search quality worth dedicated investment regardless of platform edition.
Frequently Asked Questions
What is a Magento extension?
A Magento extension is a modular software package that adds or modifies functionality in a Magento or Adobe Commerce store — installed via the Adobe Commerce Marketplace or Composer, covering everything from payment gateways and shipping integrations to product search enhancement and custom checkout flows.
What is Elasticsearch in Magento 2?
Elasticsearch (and its fork OpenSearch) is Magento 2’s required search engine, indexing product attributes and returning relevance-ranked results for storefront searches. Magento 2.4.8 requires OpenSearch 2.19 or Elasticsearch 8.17. Default Magento implements basic Elasticsearch capabilities; search extensions add merchandising rules, synonyms, AI reranking, and advanced autocomplete on top of this foundation.
Is Magento now Adobe?
Yes — Adobe acquired Magento in 2018. The platform now exists as Adobe Commerce (enterprise edition, cloud or on-premises) and Magento Open Source (free community edition). Adobe Commerce includes native Live Search powered by Adobe Sensei AI; Magento Open Source requires third-party extensions for equivalent functionality.
How do you check if a product is in stock in Magento 2?
In the admin panel, navigate to Catalog → Products and check the Quantity column. In code, use the StockRegistryInterface injected via dependency injection to call getStockItem($productId) and retrieve getIsInStock() — or use the MSI GetProductSalableQty service for multi-source inventory environments.
How do you get product stock status in Magento 2?
Use the StockRegistryInterface via dependency injection to get the full stock item object for a product ID — it returns quantity, in-stock boolean, manage-stock setting, and backorder configuration. For MSI (multi-source inventory), use the GetSalableQuantityDataBySku service instead. The REST API endpoint GET /rest/V1/stockItems/{productSku} provides the same data without custom PHP.
