No results foundCheck the spelling, or search in English with simpler keywords.QwenBridge turns a sentence typed into your search box, in any language and typos included, into validated filters and a safe search plan. No filter maze, no zero-result pages.
Example Commerce domain pack: the same engine works for any domain.
Shoppers say “black Nike, size 42, under 100 EUR” once. QwenBridge sets brand, color, size and price for them.
Typos are corrected, other languages are understood, and empty searches get recovery and suggestions.
Injection, jailbreak and obfuscation attempts are stopped before they reach your index or a model.
Each scene runs the same query twice: once through plain keyword search, once through QwenBridge. Field names and statuses match the real v2 API.

Script and model-based detection, mixed-script segments, text direction and Unicode normalization.
Per language and per tenant. URLs, amounts, SKUs and acronyms are never changed. Four modes, from suggest-only to aggressive.
Translates the query into configured languages, preserves identifiers, and fuses retrieval across them.
Intent and constraints in a versioned QueryIR. Every value quotes the user’s words, with confidence and evidence.
12 detector families, a central default-deny policy engine, approvals, rate limits, quotas and tenant isolation.
Rank fusion, adaptive planning, reranking, zero-result recovery and suggestions.
Commerce and Library packs, a connector-pack SPI, a plugin SDK, signed packs, offline licences and editions.
SmallRye Health, Micrometer metrics with latency histograms, OpenTelemetry tracing and structured logs.
Call it over REST, stream it over SSE, or use an SDK. The Java SDK depends only on Jackson; the TypeScript SDK has no runtime dependencies. Both are tested against the same real server.

curl -s http://localhost:8080/q/health/readyQwenBridge runs as one process inside your network. No external AI API, no SaaS, no mandatory database. The same rules apply to every future phase.
Runs on a local Ollama-compatible model, or your own HTTP gateway. Nothing is sent to a third party.
No mandatory internet connection, SaaS service or third-party MCP server.
In-process index and local state by default. OpenSearch and Redis are optional.
Default-deny policy engine, tenant isolation, rate limits and masked secrets in every error.
Every extracted value quotes its source, with confidence and evidence attached to each answer.
Domain packs, connector SPI, plugin SDK and policy packs. The core depends only on Jackson.
Laptop baselines from the 1.0 release notes. Measure your own environment before production.
The engine is plain Java with no framework. Quarkus is the only application framework, and module rules are enforced by architecture tests.

“black nike shoes size 42 under 100 euro”Discovers modules, classes, methods, dependency injection, routes and configuration, and keeps a searchable, versioned memory that points to exact files.
“Which classes depend on PaymentService?”Module, class, call and service graphs. Circular dependencies, boundary violations, change-impact analysis and request paths from route to database.
“What could break if this class changes?”Read-only adapters for Kubernetes, Prometheus, OpenSearch, HAProxy and more: what runs where, what routes to what, and what could not be observed.
“Which pods serve POST /api/v1/payment?”Correlates code, logs, traces, metrics, deployments and config changes into a timeline with evidence-backed hypotheses. Correlation is never presented as proof.
“Why did the payment API return 500 at 14:30?”What exists, where it exists, how it is connected, how it behaves, what changed, what is missing, what failed, and why.
Only phase 1 is available today. Phases 2 to 5 describe planned capabilities; each will be implemented and verified separately before it is released.
Around 60 guides and 58 architecture decision records.
