AI Site Search for Ecommerce: Fixing the Search Box Shoppers Rely On

AI site search uses machine learning and language understanding to return relevant products even when shoppers misspell words, use different vocabulary from your catalog, or describe what they need rather than naming it. For Adobe Commerce stores, Adobe Live Search is the native option: a SaaS search service that replaces the default search with search-as-you-type, AI-driven facets and ranking, synonyms, merchandising rules and, for English catalogs, semantic search. Whatever tool you use, the biggest gains usually come from auditing zero-result queries, synonyms, typo handling and merchandising before you change technology.

This guide explains what Adobe Live Search does, how it compares with the default OpenSearch-based search, and gives a search audit checklist you can run on any store.

Why the search box deserves attention

Shoppers who search are telling you exactly what they want. When search fails, they rarely browse categories as a fallback; they leave. Common failures are easy to spot once you look:

• "No results" for a product you sell, because the shopper used a different word ("sofa" vs "couch").
• Misspellings or plural forms that miss obvious matches.
• Results ranked by keyword frequency instead of relevance, so accessories appear above the main product.
• Out-of-stock items at the top.
• Facets that do not match the result set, or too many irrelevant ones.

What Adobe Live Search does

According to Adobe's Experience League documentation, Live Search replaces the standard Adobe Commerce search with a hosted service included in the Adobe Commerce license. Its main capabilities are:

• Search as you type: a popover with suggested products and thumbnails, starting from two characters.
• Typo tolerance: an exact search first, then a fuzzy search if nothing matches.
• Facets: merchant-selected filters such as brand, color and price, with dynamic ordering.
• AI-powered ranking and faceting: adjusting results and facets using in-session shopper behavior.
• Semantic search: interprets meaning so relevant products appear even when wording differs. Adobe states it is available for Adobe Commerce 2.4.4 and newer, for English-language catalogs, and is a simple on/off setting.
• Synonyms: one-way and two-way synonyms, managed in the Admin.
• Merchandising rules: if-then rules to boost, bury, pin or hide products for particular queries.
• Dashboards: reporting on popular searches, zero-result searches and click-through, fed by storefront events.

Adobe also documents boundaries and limits, including caps on synonyms and rules per store view, and notes that rules and manual rankings apply only under the default sort order. Read those limits before planning a large synonym library. Headless storefronts must set up the storefront events themselves for the AI features and dashboards to work.

Live Search vs default OpenSearch search

Adobe Commerce and Magento Open Source ship with catalog search built on OpenSearch. It is capable and fully under your control, but relevance tuning is a developer task. Live Search moves search to an Adobe-hosted service and adds the AI and merchandising tools above, but it is only available for Adobe Commerce.

For stores staying on OpenSearch, much can still be improved through attribute weighting, analyzers, synonyms and indexing hygiene. Our Magento OpenSearch guide covers setup and tuning, and third-party search services are another route.

Search audit checklist

Run this audit before and after any search change. It works on any platform. Pull the last 30 to 90 days of search queries from your analytics or search dashboard.

1. Zero-result queries

• List the top 50 queries that returned no results.
• Classify each: product you sell (vocabulary gap), misspelling, product you do not sell, or nonsense.
• For vocabulary gaps, add synonyms or update product attributes. For misspellings, check typo tolerance. For products you do not sell, decide whether a helpful fallback (related category, best sellers) is better than an empty page.
• Make sure the zero-results page itself offers popular categories, trending products or a contact route.

2. Synonyms

• Check regional and colloquial terms: "trainers" and "sneakers", "trousers" and "pants".
• Check brand and model shorthand that shoppers use.
• Use one-way synonyms where a broad term should find a narrow one but not the reverse.
• Review synonyms quarterly; outdated ones cause irrelevant results.

3. Typos and formats

• Test common misspellings of your top 20 products and brands.
• Test SKUs and part numbers with and without hyphens and spaces; B2B buyers search this way.
• Test singular and plural forms, and units ("10mm" vs "10 mm").

4. Relevance of the top results

• For your top 20 queries, check whether the first row of results contains what most shoppers want.
• Look for accessories outranking main products, and out-of-stock items ranking high.
• Check that searchable attributes and their weights reflect what shoppers actually type.

5. Merchandising

• Use rules for genuine business needs: seasonal boosts, new ranges, clearing stock.
• Document every rule with an owner and an end date, and remove expired ones.
• Remember that in Live Search, rules only apply under the default sort.

6. Facets and filters

• Check that facets match the result set and are ordered by usefulness.
• Remove facets with one value or inconsistent values (for example, "Navy", "navy blue" and "Blue - Navy").

7. Speed and experience

• Measure how quickly suggestions appear while typing, on mobile.
• Check search results pages against Core Web Vitals, since heavy search widgets can hurt interaction responsiveness. Our Magento performance optimization work often includes search pages for this reason.

8. Measurement

• Track search usage rate, zero-result rate, search exit rate, click-through from results and conversion for sessions with search.
• Re-run the audit after each change and compare.

Search and conversational shopping

Chat-style assistants depend on good search underneath: when a shopper asks a chatbot for "a warm jacket for hiking", the assistant still needs a reliable product retrieval layer. Improving search first makes any later assistant more accurate. See our guide to the AI chatbot for ecommerce for how the two connect.

FAQ

Is Adobe Live Search available for Magento Open Source?

No. Live Search is an Adobe Commerce service. Open Source stores use the built-in OpenSearch search, an extension, or a third-party search service.

Does semantic search work in every language?

Not at present. Adobe documents semantic search for English-language catalogs only; check the current documentation if you sell in other languages.

How many synonyms should we add?

Start from evidence: the vocabulary gaps in your zero-result queries. A short, accurate list beats a long one, and Live Search has a per-store-view limit.
