embeddings

addDocuments

• addDocuments(documents, options?): Promise<void | string[]>

• Parameters

  • documents: DocumentInterface<Record<string, any>>[]

  • Optional options: AddDocumentOptions

  Returns Promise<void | string[]>

addVectors

• addVectors(vectors, documents, options?): Promise<void | string[]>

• Parameters

  • vectors: number[][]

  • documents: DocumentInterface<Record<string, any>>[]

  • Optional options: AddDocumentOptions

  Returns Promise<void | string[]>

asRetriever

• asRetriever(kOrFields?, filter?, callbacks?, tags?, metadata?, verbose?): VectorStoreRetriever<VectorStoreInterface>

• Parameters

  • Optional kOrFields: number | Partial<VectorStoreRetrieverInput<VectorStoreInterface>>

  • Optional filter: string | object

  • Optional callbacks: Callbacks

  • Optional tags: string[]

  • Optional metadata: Record<string, unknown>

  • Optional verbose: boolean

  Returns VectorStoreRetriever<VectorStoreInterface>

delete

• delete(_params?): Promise<void>

• Parameters

  • Optional _params: Record<string, any>

  Returns Promise<void>

similaritySearch

• similaritySearch(query, k, filter, callbacks): Promise<DocumentInterface<Record<string, any>>[]>

• Parameters

  • query: string

  • k: number

  • filter: undefined | string | object

  • callbacks: undefined | Callbacks

  Returns Promise<DocumentInterface<Record<string, any>>[]>

similaritySearchVectorWithScore

• similaritySearchVectorWithScore(query, k, filter?): Promise<[DocumentInterface<Record<string, any>>, number][]>

• Parameters

  • query: number[]

  • k: number

  • Optional filter: string | object

  Returns Promise<[DocumentInterface<Record<string, any>>, number][]>

similaritySearchWithScore

• similaritySearchWithScore(query, k, filter, callbacks): Promise<[DocumentInterface<Record<string, any>>, number][]>

• Parameters

  • query: string

  • k: number

  • filter: undefined | string | object

  • callbacks: undefined | Callbacks

  Returns Promise<[DocumentInterface<Record<string, any>>, number][]>

Optional maxMarginalRelevanceSearch

• maxMarginalRelevanceSearch(query, options, callbacks): Promise<DocumentInterface<Record<string, any>>[]>

• Return documents selected using the maximal marginal relevance. Maximal marginal relevance optimizes for similarity to the query AND diversity among selected documents.

  Parameters

  • query: string

    Text to look up documents similar to.

  • options: MaxMarginalRelevanceSearchOptions<string | object>

  • callbacks: undefined | Callbacks

  Returns Promise<DocumentInterface<Record<string, any>>[]>

  • List of documents selected by maximal marginal relevance.
