Discovery Accelerator cannot search within ZIP files. Evidence. Documentation.

Hello, team.

Is a fact, that Discovery Accelerator cannot search within ZIP files. I've made several test cases and haven't found items with content inside ZIP file.

In this case EV indexes only file name and extension in ZIP file.

Can you please provide me documentation, where I can find this is really impossible to find items within ZIP file, and this isn't my fault and system misconfiguration. I have to provide this evidence for my boss.

Thanks.
