Open a command palette, and type Quick note search.
Type seach words and/or #-prefixed tags. (ex. #vscode debug)
When input multiple words, tags are treated as "OR" condition, while words are "AND" condition. And only files matched with tags AND matched with words are in result.
Text contents of files and file names are searched with words.
Search words are case-insensitive.
Tag format is YAML-like, but only list format enclosed by [ and ] is allowed, and must be immediately after beginning of each file, as an example below:
---
tags: [ programming, vscode ]
---
# How to debug extension
Bla bla bla...
