Support proper updates in StringIndex about voyager HOT 3 OPEN

Hi @dylanrb123
Just as a doubt, does that imply doing a search algorithm on the HNSW algorithm to find the elements that already exist?

Hi @karchx, I updated the description of the issue to make it more clear. I'm not sure I fully understand your question but let me know if anything is still unclear.

@dylanrb123
you mean like checking If we already have this name in it and if use index of that name ?
eg.

public void addItem(String name, float[] vector) {
    int updateIndex = names.indexOf(name);
    if (updateIndex==-1) {
      int nextIndex = names.size();
      index.addItem(vector, nextIndex);
      names.add(name);
    } else {
      index.addItem(vector, updateIndex);
    }
}
