Methods

  • Combines the results of the similaritySearch and keywordSearch methods and returns the top 'k' documents based on a combination of similarity and keyword matching.

    Parameters

    • query: string

      The query to use for the hybrid search.

    • similarityK: number

      The number of top similar documents to return.

    • keywordK: number

      The number of top documents to return that match the keywords.

    • Optional callbacks: CallbackManager | (BaseCallbackHandler | BaseCallbackHandlerMethodsClass)[]

      Optional callbacks to pass to the similaritySearch method.

    Returns Promise<SearchResult[]>

    A promise that resolves to an array of search results. Each result is a tuple containing a Document, its combined score, and its ID.

  • Performs a keyword search on the Supabase database using the provided query and returns the top 'k' documents that match the keywords.

    Parameters

    • query: string

      The query to use for the keyword search.

    • k: number

      The number of top documents to return that match the keywords.

    Returns Promise<SearchResult[]>

    A promise that resolves to an array of search results. Each result is a tuple containing a Document, its similarity score multiplied by 10, and its ID.

  • Performs a similarity search on the Supabase database using the provided query and returns the top 'k' similar documents.

    Parameters

    • query: string

      The query to use for the similarity search.

    • k: number

      The number of top similar documents to return.

    • Optional _callbacks: CallbackManager | (BaseCallbackHandler | BaseCallbackHandlerMethodsClass)[]

      Optional callbacks to pass to the embedQuery method.

    Returns Promise<SearchResult[]>

    A promise that resolves to an array of search results. Each result is a tuple containing a Document, its similarity score, and its ID.
