Method to add documents to the Weaviate index. It first generates vectors for the documents using the embeddings, then adds the vectors and documents to the index.
Array of documents to be added.
Optional options: { Optional parameter that can include specific IDs for the documents.
Optional ids?: string[]An array of document IDs.
Method to add vectors and corresponding documents to the Weaviate index.
Array of vectors to be added.
Array of documents corresponding to the vectors.
Optional options: { Optional parameter that can include specific IDs for the documents.
Optional ids?: string[]An array of document IDs.
Method to delete data from the Weaviate index. It can delete data based on specific IDs or a filter.
Object that includes either an array of IDs or a filter for the data to be deleted.
Optional filter?: WeaviateFilterOptional ids?: string[]Promise that resolves when the deletion is complete.
Return documents selected using the maximal marginal relevance. Maximal marginal relevance optimizes for similarity to the query AND diversity among selected documents.
Text to look up documents similar to.
Optional _callbacks: undefinedMethod to perform a similarity search on the stored vectors in the Weaviate index. It returns the top k most similar documents and their similarity scores.
The query vector.
The number of most similar documents to return.
Optional filter: WeaviateFilterOptional filter to apply to the search.
An array of tuples, where each tuple contains a document and its similarity score.
Method to perform a similarity search on the stored vectors in the Weaviate index. It returns the top k most similar documents, their similarity scores and embedding vectors.
The query vector.
The number of most similar documents to return.
Optional filter: WeaviateFilterOptional filter to apply to the search.
An array of tuples, where each tuple contains a document, its similarity score and its embedding vector.

Static fromStatic method to create a new WeaviateStore instance from a list of
texts. It first creates documents from the texts and metadata, then
adds the documents to the Weaviate index.
