Explore each search capability — from semantic understanding to visual product discovery.
Transformer-based query understanding that matches intent — not just keywords. Queries and catalog items share the same 768-dimensional embedding space for conceptual relevance scoring.
From query to conversion
Natural language decomposed into structured signals. Results re-ranked by individual behavioral affinity.

Five layers of search intelligence
From semantic understanding to personalized re-ranking — each layer adds precision to every query.
Semantic Vector Search
Queries are embedded into the same behavioral vector space as catalog items using BaseModel.ai representations. Semantic matching retrieves conceptually relevant results — even when exact keyword matches don't exist.
Personalized Re-Ranking
Search results are re-ranked in real time based on each user's behavioral profile. Two users searching the same query see different result orderings — optimized for their individual purchase probability.
Dynamic Faceting & Filtering
Facets are generated dynamically from the result set — not pre-computed. Filter counts update in real time as users narrow their search, ensuring zero dead-end filter combinations.
Natural Language Query Understanding
An NLU layer parses complex natural language queries into structured intent, entity, and filter components. 'Red dress under $50 for summer' is decomposed into color, category, price, and seasonality signals.
Merchandising Controls
Business rules overlay algorithmic ranking — pin items, boost brands, bury out-of-stock, and apply promotional rules. Visual merchandising tools let non-technical teams control search results without code.
Query execution pipeline
Every query traverses five stages — from raw text to personalized, merchandised results — in under 15 milliseconds.
Query Processing
Tokenization, spell correction, NLU parsing, intent classification
Retrieval
Hybrid BM25 + vector search with configurable fusion weights
Scoring
Multi-signal relevance scoring (textual, behavioral, business rules)
Re-Ranking
Personalized re-ranking using real-time behavioral embeddings
Post-Processing
Faceting, deduplication, diversity injection, result decoration
Proof in production
Proven in head-to-head A/B tests
Live-traffic A/B tests on client e-commerce platforms. Baselines anonymized per client agreement; uplifts are relative to each baseline.
vs. Native search of a leading commerce platform
Full-funnel A/B test on live traffic; sessions tracked across engagement, conversion, and revenue contribution.
| KPI (search sessions) | Platform native | Synerise AI Search | Uplift |
|---|---|---|---|
| Click-through rate | 3.42% | 11.41% | +233% |
| Conversion rate | 0.61% | 1.62% | +165% |
| Share of revenue from search | — | 12.85% | — |
Platform-native search caps engagement and conversion. Behavioral AI ranking compounds both — more clicks, more orders, and a meaningful share of total revenue flowing through search.
vs. Best-of-breed SaaS search
Three-way A/B test running ~2 weeks — platform native search, SaaS vendor, and Synerise AI Search — with traffic split across all three variants.
| KPI (search sessions) | SaaS vendor | Synerise AI Search | Uplift |
|---|---|---|---|
| Zero results rate | ~1.8% | ~1.0% | −44% |
| Core revenue | undisclosed | undisclosed | +5.0% |
| Ads revenue | undisclosed | undisclosed | +4.6% |
| Total revenue | undisclosed | undisclosed | +4.99% |
| Orders | undisclosed | undisclosed | +5.36% |
Against a dedicated SaaS search vendor, Synerise delivered measurably better outcomes across every disclosed KPI — lower zero results rate, higher revenue, more orders.
vs. In-house tuned ElasticSearch
15-day A/B test with equal traffic split between tuned ElasticSearch (variant A) and Synerise AI Search (variant B).
| KPI (search sessions) | Tuned ElasticSearch | Synerise AI Search | Uplift |
|---|---|---|---|
| Zero results rate | ~2.7% | ~0.9% | −66% (3× fewer) |
| CTR | 36.1% | 36.4% | +0.8% |
| Add-to-cart rate (30 min) | 28.0% | 27.5% | −1.8% |
| Sales conversion rate (30 min) | 9.6% | 9.5% | −1.0% |
| Core revenue | undisclosed | undisclosed | +4.8% |
| Ads revenue | undisclosed | undisclosed | +1.0% |
| Total revenue | undisclosed | undisclosed | +4.2% |
| Revenue per session | undisclosed | undisclosed | +3.7% |
| Avg. order value | undisclosed | undisclosed | +4.4% |
A well-tuned in-house ElasticSearch is a serious baseline — late-funnel conversion rates were essentially at parity. But behavioral AI ranking unlocked upside the tuned system couldn't: 3× fewer dead-end queries, larger baskets, higher revenue per session. The gap isn't in the known queries — it's in the long tail.
vs. Global market leader (e-commerce search)
A/B test on a fashion marketplace across multiple markets measuring purchase conversion in 30-min, 2h and 24h windows after search.
| KPI (search sessions) | Market leader | Synerise AI Search | Uplift |
|---|---|---|---|
| Conversion rate (30 min) | 5.18% | 6.32% | +22% |
| Conversion rate (24 h) | 8.16% | 11.12% | +36% |
| CTR | ≈ parity | ≈ parity | ≈ 0 |
| Zero results rate | ≈ parity | ≈ parity | ≈ 0 |
Parity on relevance metrics, decisive wins on conversion — and a +36% relative uplift in the best market (conversion in 24h window). Outcome: full replacement of the incumbent engine across all tested markets.
“Match on relevance. Win on conversion.”

Bayesian significanceWhy search matters
Search punches above its weight
Aggregate performance across Synerise AI Search deployments. Quality metrics computed at the query level; engagement and revenue at the search-session level.
| KPI | Average | Best observed |
|---|---|---|
| Zero results rate | ~4.8% | ~0.9% |
| Click-through rate | ~22.5% | ~26.7% |
| Add-to-cart rate (30 min) | ~9.2% | ~11.7% |
| Purchase conversion (30 min) | ~2.8% | ~3.5% |
| Share of sessions using search | ~9.6% | ~10.5% |
| Share of revenue from search | ~16.7% | ~29.7% |
~10% of sessions generate ~17% of revenue — and up to ~30% in the best-performing deployments. Improvements to search compound disproportionately on the bottom line.
