Smile How to clean empty records with only .opf

I have lot of records in my calibre database that have only .opf files an nothing else. I have two questions.

1.How can i search for these records. I tried format:false or formats=false but it doesn't work.
2. What is the reason that caused this so i can avoid this in future ?

Thanks

Run Library Maintenance (Right click the Library icon)
Once that is done. formats:false should work

As to why?
That is what is called an 'Empty Book' . Many of us use that feature (add books: empty book: <qty>) to document: 1)paper versions (only) 2)wishlist

If yours was NOT that reason, then someone or something is:
1) going into the Library/Author folder and deleting the format
2)You have merged (copied) different libraries onto each other
3)You have the Library folder on a NAS or Share and or 2 users running calibre at the same time
