Spotlight indexing cache files

I can see a couple of python scripts in indexing folders

/System/Volumes/Data/.Spotlight-V100/Store-V2/<GUID>/Cache/0000/0003/0003/12885148578.txt

Why is the spotlight keeping copies of the files in addition to the indexing metadata?

Are these temporary files and would these be auto-deleted after some known time period?
