AI search on Shopware 6.6 for an electronics retailer: 60% better relevance on staging

Native Shopware search could not deliver the autocomplete speed, ranking relevance and personalized discovery that a large, fast-moving catalogue demands. A leading German electronics retailer runs exactly that kind of catalogue on a high-traffic Shopware 6.6 storefront. It needed AI-driven on-site search that fit into the existing storefront.

We built a custom Shopware 6.6 plugin that integrates Google Cloud Vertex AI Search for Retail across the storefront: base search and result rendering, autocomplete and quick search, filtering, sorting and pagination. We added a pre-search panel with personalized recommendations, plus spell correction with query expansion. Facet logic shows only the filters that actually change the results, alongside a live total product count and per-sales-channel configuration. We worked on a dedicated staging environment with QA, in a weekly, feedback-driven cycle with the client.
