Methods

addDocuments

  • addDocuments(documents, documentOptions?): Promise<void>

  • Method to add documents to the Qdrant database. It generates vectors from the documents using the Embeddings instance and then adds the vectors to the database.

    Parameters

    • documents: Document[]

      Array of Document instances to be added to the Qdrant database.

    • OptionaldocumentOptions: QdrantAddDocumentOptions

      Optional QdrantAddDocumentOptions which has a list of JSON objects for extra querying

    Returns Promise<void>

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

addVectors

  • addVectors(vectors, documents, documentOptions?): Promise<void>

  • Method to add vectors to the Qdrant database. Each vector is associated with a document, which is stored as the payload for a point in the database.

    Parameters

    • vectors: number[][]

      Array of vectors to be added to the Qdrant database.

    • documents: Document[]

      Array of Document instances associated with the vectors.

    • OptionaldocumentOptions: QdrantAddDocumentOptions

      Optional QdrantAddDocumentOptions which has a list of JSON objects for extra querying

    Returns Promise<void>

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

ensureCollection

  • ensureCollection(): Promise<void>

  • Method to ensure the existence of a collection in the Qdrant database. If the collection does not exist, it is created.

    Returns Promise<void>

    Promise that resolves when the existence of the collection has been ensured.

similaritySearchVectorWithScore

  • similaritySearchVectorWithScore(query, k?, filter?): Promise<[Document, number][]>

  • Method to search for vectors in the Qdrant database that are similar to a given query vector. The search results include the score and payload (metadata and content) for each similar vector.

    Parameters

    • query: number[]

      Query vector to search for similar vectors in the Qdrant database.

    • Optionalk: number

      Optional number of similar vectors to return. If not specified, all similar vectors are returned.

        Description

        At least one of those conditions should match

    Returns Promise<[Document, number][]>

    Promise that resolves with an array of tuples, where each tuple includes a Document instance and a score for a similar vector.

StaticfromDocuments

  • fromDocuments(docs, embeddings, dbConfig): Promise<QdrantVectorStore>

  • Static method to create a QdrantVectorStore instance from Document instances. The documents are added to the Qdrant database.

    Parameters

    • docs: Document[]

      Array of Document instances to be added to the Qdrant database.

    • embeddings: EmbeddingsInterface

      Embeddings instance used to generate vectors from the documents.

    • dbConfig: QdrantLibArgs

      QdrantLibArgs instance specifying the configuration for the Qdrant database.

    Returns Promise<QdrantVectorStore>

    Promise that resolves with a new QdrantVectorStore instance.

StaticfromExistingCollection

  • fromExistingCollection(embeddings, dbConfig): Promise<QdrantVectorStore>

  • Static method to create a QdrantVectorStore instance from an existing collection in the Qdrant database.

    Parameters

    • embeddings: EmbeddingsInterface

      Embeddings instance used to generate vectors from the documents in the collection.

    • dbConfig: QdrantLibArgs

      QdrantLibArgs instance specifying the configuration for the Qdrant database.

    Returns Promise<QdrantVectorStore>

    Promise that resolves with a new QdrantVectorStore instance.

StaticfromTexts

  • fromTexts(texts, metadatas, embeddings, dbConfig): Promise<QdrantVectorStore>

  • Static method to create a QdrantVectorStore instance from texts. Each text is associated with metadata and converted to a Document instance, which is then added to the Qdrant database.

    Parameters

    • texts: string[]

      Array of texts to be converted to Document instances and added to the Qdrant database.

    • metadatas: object | object[]

      Array or single object of metadata to be associated with the texts.

    • embeddings: EmbeddingsInterface

      Embeddings instance used to generate vectors from the texts.

    • dbConfig: QdrantLibArgs

      QdrantLibArgs instance specifying the configuration for the Qdrant database.

    Returns Promise<QdrantVectorStore>

    Promise that resolves with a new QdrantVectorStore instance.
