How to make Obsidian Search both File Name and Content of My note at the same time

Things I have tried

Option O, and the sidebar search function

What I’m trying to do

Find a feature that does both of the above things and all I have to do is just type.

You see, Google can look through website titles AND contents. But Obsidian can’t do the same thing to search my own MD files.

Check out GitHub - scambier/obsidian-omnisearch: A search engine that "just works" for Obsidian

I don’t get the question - when you are searching something in obsidian, it actually will search both file names and content…!?
