spotlightknowledged high resource usages lead to fast battery drain and overheating

I tried a few things:

• Restarted my MacBook.
• Removed the Macintosh HD from indexing and then re-added it for indexing.
• Deleted the index completely and let indexing complete, which took only about 5 minutes.
• For a temporary fix, I forcefully killed the process, but it respawned after a while when I used Spotlight again. So, I keep killing the process whenever it starts consuming too much resources.

A few things I’ve noticed about the problem:

• The process doesn’t suddenly start consuming resources; it takes about a few minutes before the resource usage skyrockets.
• Even if I let the process run for an hour, it still continues to consume resources.
• Killing the process instantly respawns it, but the resource usage remains within the limit for a while.
