Biwem inc.

Biwem Search Autocomplete brings real-time, intelligent autocomplete suggestions to your WooCommerce store. Visitors find what they’re looking for in seconds — even if they misspell, abbreviate, or only know the SKU.
The plugin is built around four ideas:
<ol>
<li>Speed. Suggestions appear as the visitor types, with multi-level caching that keeps response times low even on shared hosting.</li>
<li>Forgiveness. Built-in fuzzy matching catches typos and missing letters automatically. Searching “trapno” still finds the trapano.</li>
<li>Smart matching. Beyond plain titles, the plugin also matches product SKUs and EAN/GTIN codes, so warehouse and B2B users find products by code instantly.</li>
<li>Compatibility. Works with any theme, any WooCommerce setup, any cache plugin. No assumptions about your stack.</li>
</ol>
<h4>What’s included</h4>
<ul>
<li>Real-time autocomplete suggestions in the search box</li>
<li>Configurable number of product / post / page suggestions per query (you choose how many)</li>
<li>Multilingual smart fuzzy matching — automatic typo recovery in English, Italian, Spanish, French, and German (handles missing letters, swapped letters, vowel substitution)</li>
<li>Automatic accent normalization — café/über/straße/niño/français all matched without typing the accents</li>
<li>SKU and EAN/GTIN exact match (a customer who knows the code finds the product immediately)</li>
<li>Multi-content search — products, blog posts, and pages in a single dropdown (toggle each independently)</li>
<li>Product thumbnails in the dropdown</li>
<li>Product price display with regular/sale formatting (uses WooCommerce currency settings)</li>
<li>Loading indicator while suggestions are fetched</li>
<li>Out-of-stock filter — hide unavailable products from suggestions</li>
<li>Multi-level caching (in-memory + 10-minute transient) for fast responses</li>
<li>Translation-ready (compatible with WPML, Polylang and Loco Translate)</li>
<li>5 bundled admin languages out of the box: English, Italian, Spanish, French, German</li>
<li>Works with any theme — no required modifications</li>
<li>Drop-in shortcode <code>[wcsa_search_autocomplete]</code> with 4 design styles</li>
</ul>
<h4>Privacy-first by design</h4>
This plugin makes zero external calls. Everything runs on your own server. No data is sent anywhere — ever.
<ul>
<li>No phone-home updates. Updates come from WordPress.org.</li>
<li>No usage tracking. No statistics, analytics, or telemetry are collected.</li>
<li>No GeoIP lookup. The plugin does not look up your visitors’ country.</li>
</ul>
The plugin is fully GDPR-friendly.
<h4>Pro version</h4>
A separate Pro version with advanced features is available at <a href="https://www.biwem.it/autocomplete" rel="nofollow ugc">https://www.biwem.it/autocomplete</a>. Pro features include:
<ul>

</ul>

<h3>External services</h3>
This plugin does not connect to, send data to, or rely on any external services. All functionality runs entirely on your own server:
<ul>
<li>Product search and SKU/EAN lookups are processed locally via WordPress’s own database. No third-party APIs are involved.</li>
<li>The plugin’s REST endpoint <code>/wp-json/wcsa/v1/suggestions</code> is internal — it is served by your own WordPress installation, on your own domain, and is called only by the front-end autocomplete script running in the visitor’s browser.</li>
</ul>
No analytics, no telemetry, no tracking, no remote calls of any kind.
