constructor

new Neo4jGraphRAGEngine(deps): Neo4jGraphRAGEngine
Parameters
- deps: Neo4jGraphRAGEngineDeps
Returns Neo4jGraphRAGEngine
- Defined in src/memory/retrieval/graph/graphrag/Neo4jGraphRAGEngine.ts:84

Methods

initialize

initialize(config): Promise<void>
Initialize the engine with configuration
Parameters
- config: GraphRAGConfig
Returns Promise<void>
Implementation of IGraphRAGEngine.initialize
- Defined in src/memory/retrieval/graph/graphrag/Neo4jGraphRAGEngine.ts:86

ingestDocuments

ingestDocuments(documents): Promise<{
    entitiesExtracted: number;
    relationshipsExtracted: number;
    communitiesDetected: number;
    documentsProcessed: number;
}>
Ingest documents: extract entities/relationships, build graph, detect communities, generate summaries.
Parameters
- documents: {
      id: string;
      content: string;
      metadata?: Record<string, MetadataValue>;
  }[]
Returns Promise<{
    entitiesExtracted: number;
    relationshipsExtracted: number;
    communitiesDetected: number;
    documentsProcessed: number;
}>
Implementation of IGraphRAGEngine.ingestDocuments
- Defined in src/memory/retrieval/graph/graphrag/Neo4jGraphRAGEngine.ts:128

removeDocuments

removeDocuments(documentIds): Promise<{
documentsRemoved: number;
communitiesDetected: number;
}>
Remove one or more previously-ingested documents from the graph.

This subtracts the document's entity/relationship contributions and recomputes communities. It is used to keep GraphRAG in sync when a source document is deleted or moved out of indexed categories.
Parameters
- documentIds: string[]
Returns Promise<{
documentsRemoved: number;
communitiesDetected: number;
}>
Implementation of IGraphRAGEngine.removeDocuments
- Defined in src/memory/retrieval/graph/graphrag/Neo4jGraphRAGEngine.ts:238

globalSearch

globalSearch(query, options?): Promise<GlobalSearchResult>
Global search: answers broad questions using community summaries. Best for "What are the main themes?" type questions.
Parameters
- query: string
- Optional options: GraphRAGSearchOptions
Returns Promise<GlobalSearchResult>
Implementation of IGraphRAGEngine.globalSearch
- Defined in src/memory/retrieval/graph/graphrag/Neo4jGraphRAGEngine.ts:278

localSearch

localSearch(query, options?): Promise<LocalSearchResult>
Local search: finds specific entities and their context. Best for "Tell me about X" type questions.
Parameters
- query: string
- Optional options: GraphRAGSearchOptions
Returns Promise<LocalSearchResult>
Implementation of IGraphRAGEngine.localSearch
- Defined in src/memory/retrieval/graph/graphrag/Neo4jGraphRAGEngine.ts:377

  }
  - Optional type?: string
  - Optional limit?: number
Returns Promise<GraphEntity[]>
Implementation of IGraphRAGEngine.getEntities
- Defined in src/memory/retrieval/graph/graphrag/Neo4jGraphRAGEngine.ts:562

getRelationships

getRelationships(entityId): Promise<GraphRelationship[]>
Get all relationships for an entity
Parameters
- entityId: string
Returns Promise<GraphRelationship[]>
Implementation of IGraphRAGEngine.getRelationships
- Defined in src/memory/retrieval/graph/graphrag/Neo4jGraphRAGEngine.ts:581

getCommunities

getCommunities(level?): Promise<GraphCommunity[]>
Get community hierarchy
Parameters
- Optional level: number

Implementation of IGraphRAGEngine.getCommunities
- Defined in src/memory/retrieval/graph/graphrag/Neo4jGraphRAGEngine.ts:604

getStats

getStats(): Promise<{
    totalEntities: number;
    totalRelationships: number;
    totalCommunities: number;
    communityLevels: number;
    documentsIngested: number;
}>
Get statistics

Returns Promise<{
    totalEntities: number;
    totalRelationships: number;
