The Problem: Standard Search is a Conversion Killer

Standard OpenCart search relies on exact keyword matching (SQL LIKE):

Typo Trap: "samsun" → 0 results

Synonym Barrier: "notebook" won't find "laptops"

Intent Blindness: doesn't understand "warm clothes for winter"

Attribute Failure: "16GB RAM" buried in attributes gets missed

Multilingual Pain: each language needs separate synonym tables

Dumb Filters: standard facets sort by count — irrelevant brands float to top

High Bounce Rate: 80% of users leave after one poor search



The Solution: Hybrid AI Engine + Smart Filters

AI Search uses a Hybrid Semantic Engine combining Vector Embeddings (meaning) with Trigram Indexing (precision) and exact-match boost (SKU). 92.7% relevance.

NEW: Faceted AI Filters attach to the search page with zero Layout edits — categories, brands, OC filter groups, attributes, price slider, stock — all with AJAX, exclude-self counting and AI-relevance sorting.

FAQ

Q: Does it work on OpenCart 3?
A: Yes. Tested on OC 3.0.0.0 – 3.0.5.0 and 4.0.2.0 – 4.1.0.3. Same ZIP.

Q: Will it slow down my site?
A: No. AI runs on our GPU cloud or your VPS. Search <200ms. Facets cached 15min.

Q: Do the AI Filters work with my theme?
A: Yes. Attaches via native event hooks (column_left, content_top) — no theme edits, no Layout clicks. Works with Default, Journal3, Stylish, etc.

Q: What is AI Relevance Sorting for filters?
A: Unique feature. Standard filters sort by count. AI Search sums semantic relevance scores per option — so for "designer laptop", brands with highly-relevant products (Apple) rank above brands with more but less-relevant products.

Q: Which languages?
A: 100+ including English, Ukrainian, Russian, German, Polish. Mixed-language queries ("iphone черный") work.

Q: What's Self-Hosted?
A: $149 one-time. You run Ollama on your VPS. No data leaves your server. GDPR/banking/medical-compliant.

Q: What does Hybrid Scoring do?
A: Semantic AI (70%) + exact-match (30%). SKUs return exact first; natural language benefits from semantics. Weights tunable.

Q: What is HNSW Fast Mode?
A: MariaDB 11.7+ native VECTOR INDEX. Auto-detected, one-click migration, 10-20× faster for 10,000+ products.

Q: Can I customize the Filters panel look?
A: Yes. Design tab has live mockups + color pickers for 9 CSS variables (accent, text, headings, chips, borders, backgrounds). Plus full FAB customization.

Q: What if the AI server is down?
A: Circuit Breaker reverts to standard OpenCart search instantly.

Q: Shared hosting OK?
A: Yes for SaaS (PHP 7.4+, outbound HTTPS). Self-Hosted needs VPS with AVX2.
