How can I find sites with blogspot infrastructure?

Hello, I knew how to do this before but I forgot.
When I typed keywords + blogspot.com and searched, for example all Tech Blogspot sites encountered results.

But I don't know how to search on google like this. The search was made with a special type.

My goal is to learn about websites that use the relevant keyword-driven blogspot.com infrastructure.
how can I do that?

Ok, I found how I can do it.
If anyone wonders;

site: blogspot.com daily news

This should do the trick: https://www.google.com/search?q=sit...69i57j69i58.3233j0j7&sourceid=chrome&ie=UTF-8

site:blogspot.com your keyword
