There was a problem hiding this comment.
Is there an issue with using the out-of-scope vectorReader here? I wasn't sure about the lifetime of it, whether there could be an issue. Again, new to all this.

From what I can tell, there's no ability with the CLI to append data onto an existing index; running IndexBuilder starts afresh.
This PR adds an
--appendparameter to IndexBuilder, which attempts to load an existing index, and calls theVectorIndex::AddIndexfunction if it already exists.I'm pretty new to C++ (from C#, so look out), so there are some changes I'm not totally confident about. But it seems pretty simple.
