Describe the issue

as title mentioned, log.json not updated its results over time.

This significantly hampers debugging and tracking the status and error messages of the index. Additionally, could a complete date and timestamp be added to the indexing-engine.log? Could a timestamp also be added to

logs.json?

Steps to reproduce

running index procedure

The issue arises because the overall runtime is too long, and I want to see detailed error messages and content. However, I noticed that logs.json does not update its content in real time.

The logs in indexing-engine.log provide much more detail than logs.json, and will update as the system progresses.
