OptionalfilterOptionalnamespaceOptionaluseThis method adds documents to Upstash database. Documents are first converted to vectors using the provided embeddings instance, and then upserted to the database.
Array of Document objects to be added to the database.
Optionaloptions: { Optional object containing array of ids for the documents.
Optionalids?: string[]OptionalusePromise that resolves with the ids of the provided documents when the upsert operation is done.
This method adds the provided vectors to Upstash database.
Array of vectors to be added to the Upstash database.
Array of Document objects, each associated with a vector.
Optionaloptions: { Optional object containing the array of ids foor the vectors.
Optionalids?: string[]Promise that resolves with the ids of the provided documents when the upsert operation is done.
This method deletes documents from the Upstash database. You can either provide the target ids, or delete all vectors in the database.
Object containing either array of ids of the documents or boolean deleteAll.
Promise that resolves when the specified documents have been deleted from the database.
This method performs a similarity search in the Upstash database over the existing vectors.
Query vector for the similarity search.
The number of similar vectors to return as result.
Optionalfilter: stringPromise that resolves with an array of tuples, each containing Document object and similarity score. The length of the result will be maximum of 'k' and vectors in the index.
StaticfromThis method creates a new UpstashVector instance from an array of Document instances.
The docs to be added to Upstash database.
Embedding interface of choice, to create the embeddings.
Object containing the Upstash database configs.
Promise that resolves with a new UpstashVector instance
StaticfromThis method creates a new UpstashVector instance from an existing index.
Embedding interface of the choice, to create the embeddings.
Object containing the Upstash database configs.
StaticfromThis method creates a new UpstashVector instance from an array of texts. The texts are initially converted to Document instances and added to Upstash database.
The texts to create the documents from.
The metadata values associated with the texts.
Embedding interface of choice, to create the text embeddings.
Object containing the Upstash database configs.
Promise that resolves with a new UpstashVector instance.
The main class that extends the 'VectorStore' class. It provides methods for interacting with Upstash index, such as adding documents, deleting documents, performing similarity search and more.
