I think operating system is much more common of a term than OpenSearch?

I think Go would be much more suitable to OpenSearch rather than to an operating system?

And the title says “OS”, not “an OS”, leading me to think that OS was a proper noun. Is that so crazy?

Anyway, the title is a bit vague, writing “an operating system” would just be better for everybody.
