Vectara provides a way to add documents directly via their API. This API handles pre-processing and chunking internally in an optimal manner. This method is a wrapper to utilize that API within LangChain.
An array of VectaraFile objects representing the files and their respective file names to be uploaded to Vectara.
A Promise that resolves to the number of successfully uploaded files.
Optional kOrFields: number | Partial<VectorStoreRetrieverInput<VectaraStore>>Optional filter: VectaraFilterOptional callbacks: CallbacksOptional tags: string[]Optional metadata: Record<string, unknown>Optional verbose: booleanPerforms a similarity search and returns documents.
The query string for the similarity search.
Optional k: numberOptional. The number of results to return. Default is 10.
Optional filter: VectaraFilterOptional. A VectaraFilter object to refine the search results.
A Promise that resolves to an array of Document objects.
Throws an error, as this method is not implemented. Use similaritySearch or similaritySearchWithScore instead.
