Weaviate - support named vectors to create embeddings on multiple fields for the same weaviate class

[IzioDev]

Checked

• I searched existing ideas and did not find a similar one
• I added a very descriptive title
• I've clearly described the feature request and motivation for it

Feature request

Currently, Weaviate lib args is limitating:

export interface WeaviateLibArgs {
    client: WeaviateClient;
    /**
     * The name of the class in Weaviate. Must start with a capital letter.
     */
    indexName: string;
    textKey?: string;
    metadataKeys?: string[];
    tenant?: string;
}

the textKey is a single string and same for Document.

the idea would be to support multi pageContent for Document (a Record/Dictionary) and have not just textKey but rather textKeys as string[]

Motivation

I'm building a similarity categorizer, and I'd like to keep datastructure as lean as possible. Weaviate allows to create a vector on a field basis.

Meaning I could have:

{
  "title": string,
  "description": string,
  "content": string,
}

and yet create a vector for each of these fields

Proposal (If applicable)
