Methods

  • Method to add an array of documents to the Tigris database.

    Parameters

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

      An array of Document instances to be added to the Tigris database.

    • Optional options: string[] | {
          ids?: string[];
      }

      Optional parameter that can either be an array of string IDs or an object with a property 'ids' that is an array of string IDs.

    Returns Promise<void>

    A Promise that resolves when the documents have been added to the Tigris database.

  • Method to add vectors to the Tigris database.

    Parameters

    • vectors: number[][]

      An array of vectors to be added to the Tigris database.

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

      An array of Document instances corresponding to the vectors.

    • Optional options: string[] | {
          ids?: string[];
      }

      Optional parameter that can either be an array of string IDs or an object with a property 'ids' that is an array of string IDs.

    Returns Promise<void>

    A Promise that resolves when the vectors have been added to the Tigris database.

  • Method to perform a similarity search in the Tigris database and return the k most similar vectors along with their similarity scores.

    Parameters

    • query: number[]

      The query vector.

    • k: number

      The number of most similar vectors to return.

    • Optional filter: object

      Optional filter object to apply during the search.

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

    A Promise that resolves to an array of tuples, each containing a Document and its similarity score.

  • Static method to create a new instance of TigrisVectorStore from an array of Document instances.

    Parameters

    • docs: Document<Record<string, any>>[]

      An array of Document instances to be added to the Tigris database.

    • embeddings: EmbeddingsInterface

      An instance of Embeddings to be used for embedding the documents.

    • dbConfig: TigrisLibArgs

      An instance of TigrisLibArgs to be used for configuring the Tigris database.

    Returns Promise<TigrisVectorStore>

    A Promise that resolves to a new instance of TigrisVectorStore.

  • Static method to create a new instance of TigrisVectorStore from an existing index.

    Parameters

    • embeddings: EmbeddingsInterface

      An instance of Embeddings to be used for embedding the documents.

    • dbConfig: TigrisLibArgs

      An instance of TigrisLibArgs to be used for configuring the Tigris database.

    Returns Promise<TigrisVectorStore>

    A Promise that resolves to a new instance of TigrisVectorStore.

  • Static method to create a new instance of TigrisVectorStore from an array of texts.

    Parameters

    • texts: string[]

      An array of texts to be converted into Document instances and added to the Tigris database.

    • metadatas: object | object[]

      Either an array of metadata objects or a single metadata object to be associated with the texts.

    • embeddings: EmbeddingsInterface

      An instance of Embeddings to be used for embedding the texts.

    • dbConfig: TigrisLibArgs

      An instance of TigrisLibArgs to be used for configuring the Tigris database.

    Returns Promise<TigrisVectorStore>

    A Promise that resolves to a new instance of TigrisVectorStore.
