AACSearch brings search, discovery, recommendations and AI answers together in one system.
Run exact full-text search, semantic and vector retrieval, fix typos and keyboard layout, control results, measure quality, and connect search to apps, sites and AI agents through the API, SDKs and MCP.

Queries come in many shapes:
WH-1000XM5exact modelбеспроводные наушнкиtypoyfeiybrb ,tcghjdjlystwrong keyboard layoutтихая посудомоечная машина для маленькой кухниnatural languageчто подойдет к этому товару?related-item questionOne retrieval mechanism handles all these query types poorly.
AACSearch uses the right strategy for each scenario:
Don't make people phrase a query the way the search engine finds convenient.
Full-text, semantic, vector and hybrid search through a single API.
Facets, filters, sorting, geo, autocomplete and typo rescue work on top of the same data model.

Zero-hit queries climb a ladder — layout, transliteration, then broadening — so shoppers still see buyable products.
Control what people see first.
Pin items, boost and bury positions, exclude results, run campaigns and validate changes with experiments.
More about MerchandisingShow relevant products and content based on context, behaviour and the relationships between items.
Similar items, related content, frequently bought together and personalized recommendations use the same data and events.
More about RecommendationsAdd answers on top of your own data.
AACSearch first finds the relevant sources, then composes the answer and returns the supporting material. People can go from the answer to the source document.
More about AI AssistantDon't guess whether search got better or worse.
Build golden query sets, compare ranking configurations, track zero-result queries and score quality with nDCG, MRR and other IR metrics.

Search shouldn't be a black box.
Query Trace and debug information help you understand:
?q=wireless headphones&debug=true
→ "_trace": { "rewrite": …, "timings": … }
→ "_explain": scoring signals per hitWhen someone asks:
“Why is this product first?”
the answer should live in the system, not in the team's guesses.
Search relevance becomes an engineering-measured system instead of a collection of gut feelings.
Moving search infrastructure touches:
So a migration shouldn't start by switching the old system off.
AACSearch helps you walk the path:
Inventory → Import → Map → Compare → Benchmark → Shadow → Cutover → Rollback
Traditional search answers a person.
Modern search infrastructure also has to serve:
AACSearch provides an MCP interface on top of the same search infrastructure.
Your agent doesn't need a separate copy of the data or a separate retrieval stack.
One index. One set of permissions. One set of sources. Different access interfaces.

So security can't be added later.
AACSearch supports access-restriction mechanisms through:
Current guarantees and the availability of each mechanism are published separately on the Trust and Security pages.
