Class for managing and operating vector search applications with Tigris, an open-source Serverless NoSQL Database and Search Platform.

Hierarchy

Constructors

Properties

FilterType: string | object
embeddings: Embeddings
lc_kwargs: SerializedFields
lc_namespace: string[] = ...

A path to the module that contains the class, eg. ["langchain", "llms"] Usually should be the same as the entrypoint the class is exported from.

lc_serializable: boolean = false
index?: any

Accessors

  • get lc_aliases(): undefined | {
        [key: string]: string;
    }
  • A map of aliases for constructor args. Keys are the attribute names, e.g. "foo". Values are the alias that will replace the key in serialization. This is used to eg. make argument names match Python.

    Returns undefined | {
        [key: string]: string;
    }

  • get lc_attributes(): undefined | SerializedFields
  • A map of additional attributes to merge with constructor args. Keys are the attribute names, e.g. "foo". Values are the attribute values, which will be serialized. These attributes need to be accepted by the constructor as arguments.

    Returns undefined | SerializedFields

  • get lc_secrets(): undefined | {
        [key: string]: string;
    }
  • A map of secrets, which will be omitted from serialization. Keys are paths to the secret in constructor args, e.g. "foo.bar.baz". Values are the secret ids, which will be used when deserializing.

    Returns undefined | {
        [key: string]: string;
    }

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: Embeddings

      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: Embeddings

      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: Embeddings

      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.

  • The name of the serializable. Override to provide an alias or to preserve the serialized module name in minified environments.

    Implemented as a static method to support loading logic.

    Returns string
