Retrieval Overview

GraWiki keeps query-time embedding and ranking in the retrieval layer rather than in the database adapter. The common contract is Retriever.

The default GraphRAG setup combines two complementary retrievers:

• TextRetriever for vector or full-text lookup over stored nodes.
• KeywordsPathRetriever for extracting keyword seeds, finding related entities, and attaching one-hop graph context.
