KID Understanding

I relocated from one country to Europe. As part of this I sold off my portfolio and opted to re-buy using interactive brokers as my platform.

I'm kinda of a little frustrated since a lot of my portfolio in my source country was Index Funds, but for some reason, the main Index funds I have looked at have a KID requirement.

I can't seem to find the ticket I opened about it but I was told it was a regulatory thing designed to protect investors. Is this correct?

Now I am just buying company stock directly which to me seems more risky vs having a combination of stocks though direct purchase and index funds.

What options do I have in order to be able to purchase Index funds in Europe.
