Sylin.Koan.Data.Vector.Connector.Milvus

Sylin.Koan.Data.Vector.Connector.Milvus

Milvus adapter for Koan vector data.

• Target framework: net10.0
• License: Apache-2.0

Capabilities

• Creates collections with a dense vector schema and JSON metadata fields
• Bulk upsert and delete via the Milvus REST API
• Hybrid similarity search with operator-aware metadata filters pushed into the query

Install

dotnet add package Sylin.Koan.Data.Vector.Connector.Milvus

Example

using Koan.Data.Abstractions.Filtering;

await Vector<MyDoc>.Save("doc-1", embedding, metadata: new { category = "support" });

// Metadata filter pushed into the search (the unified Filter AST).
var results = await Vector<MyDoc>.Search(
    embedding,
    topK: 10,
    filter: Filter.Eq("category", "support"));

The filter argument also accepts the JSON metadata-filter DSL or a dictionary; all three are parsed by the one schemaless reader. An operator the adapter cannot push down is a hard error, never a silent match-all.
