Search by SKU

What is Search by SKU?

Search by SKU lets users find a product via its unique identifier (SKU/MPN/GTIN). The engine routes the query to exact keyword fields and returns a single, authoritative match (or a tiny set of variants).

How It Works (quick)

• Detect pattern: Regex/heuristics for SKU formats; skip stemming/lemmatization.
• Route to exact fields: sku, mpn, gtin with no fuzziness by default.
• Variants & bundles: Join color/size variants; show the canonical PDP first.
• Fallbacks: If no exact hit, offer Did you mean or controlled one-edit fuzz with warnings.

Why It Matters in E-commerce

• B2B & support: Agents and buyers rely on codes.
• Zero-friction: One query → one product; ideal for returns and reorders.
• Data quality: Exposes bad/missing identifiers quickly.

Best Practices

• Normalize: Strip spaces/dashes; uppercase as needed; keep canonical stored value.
• Security & privacy: Don’t leak internal IDs; whitelist public identifiers.
• UX: Dedicated SKU mode in the search bar, or sku: prefix; render clear “Exact code match” badge.
• Analytics: Track miss rate, “near-SKU” typos, and catalog gaps.
• Feeds: Validate identifier formats on ingest; reject duplicates.

Summary

Search by SKU is a precision lookup. Route to exact fields, normalize safely, and provide gentle fallbacks without flooding noisy matches.
