Sylin.Koan.Data.Connector.OpenSearch

OpenSearch adapter for Koan vector data.

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

Capabilities

  • Automatic index provisioning with dense vector mappings
  • kNN vector search with bulk operations
  • Operator-aware metadata filtering pushed into the kNN query — the Filter → query-DSL translation is shared with Elasticsearch via Koan.Data.SearchEngine
  • Health checks and orchestration-aware configuration

Install

dotnet add package Sylin.Koan.Data.Connector.OpenSearch

Example

using Koan.Data.Abstractions.Filtering;

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

// Metadata filter pushed into the kNN query (the unified Filter AST).
var results = await Vector<MyDocument>.Search(
    embedding,
    topK: 5,
    filter: Filter.Eq("category", "docs"));

The filter argument also accepts the JSON metadata-filter DSL ({ "category": "docs" }) 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.
