I really never understood how people could store very important information in ES like it was a database.
Even if they don't understand what ES is and what a "normal" database is, I'm sure some of those people run into issues where their "db" got either corrupted of lost data even when testing and building their system around it. This is and was general knowledge at the time, it was no secret that from time to time things got corrupted and indexes needed to be rebuilt.
Doesn't happen all the time, but way greater than zero times and it's understandable because Lucene is not a DB engine or "DB grade" storage engine, they had other more important things to solve in their domain.
So when I read stories of data loss and things going South, I don't have sympathy for anyone involved other than the unsuspecting final clients. These people knew or more or less knew and choose to ignore and be lazy.
