Indx v5 and IndxCloud API v2 are coming

We have been quietly rebuilding two of the biggest pieces of Indx, and they are now ready to share. Indx v5 is the next generation of the core engine, and IndxCloud API v2 is a complete redesign of the hosted platform.

Both are available today as a beta preview.

The same pattern matching you know, now faster, leaner, and easier to integrate.

What is new in Indx v5

The v5 engine keeps the pattern matching that makes Indx resilient to messy input, and adds a set of long-requested capabilities.

• Dynamic inserts. Add documents to a live index without a rebuild.
• Hybrid search. Combine pattern matching with LLM embeddings for semantic relevance.
• Refreshed 16-bit scoring model. Finer-grained relevance scores across the board.
• Query-time field boosting. Weight fields per query instead of baking it into the index.
• Better agentic search. Improved support for AI agents querying Indx directly.
• Faster and leaner. Performance improvements with reduced memory consumption.

IndxCloud API v2

API v2 is a complete redesign of the hosted platform that takes you from raw API calls to a full control plane. Everything you need to run search in production now lives in one place.

• Visual index management. Configure indexing, field roles, and boost rules from the dashboard, with no redeploys.
• Team owned datasets. Invite your team and assign roles so the right people get the right access.
• Real time notifications. Stay informed as long running and dynamic operations complete.
• Native MCP support. Connect Indx to your AI agents and tools over the Model Context Protocol.
• Live search preview. Tune relevance and preview results against your real data, right in the dashboard.
• Hardened fault handling. A more resilient engine that recovers gracefully and keeps search online.
• Resource manager with hibernation. Configurable hibernation idles datasets when they go quiet and wakes them on demand to reclaim resources.

The auth model is simpler, the endpoints are more consistent, and the new team concept keeps your datasets organized as you scale. If you build against the hosted API, v2 is the surface to grow on.

Try the preview

The beta is open now. The fastest way in is the v5 engine on NuGet. Add the prerelease package and you are searching in minutes.

Prefer an HTTP API? IndxCloudApi v2 is now in beta and public on GitHub. Self-host it on Azure, or any provider that runs .NET, to stand up your own v2 cloud endpoint.
