If you use the query CLI with no configured vector store, we'll helpfully populate a local lancedb instance to query against. However, this index is stored in your working directory, which may have many different dataset subfolders. At a minimum this should go one folder lower: into the specific dataset folder that is being queried. Even better would be to push it into the target query directory (or latest timestamped output folder, which is what query looks for if unspecified). This way new indexing runs, which may add entities, are ensured to get properly indexed into lancedb.
