Alfred can search for files by tag. And by file names. Separately.
Apple's Spotlight conveniently combine both in its search results.
As an example, let's say I want to open one of my apps for editing markdown. I can't remember the name of the one I'm looking for.
Alfred's search comes out with 2 apps: Markdown Pro & Multimarkdown Composer.
Apple's default search comes out with all 5 apps: Markdown Pro, Multimarkdown Composer, IA Writer, Haroopad, Typora.
Knowing I would be hard press to remember the function of the 600 apps in my Mac, I tagged those that have names unrelated to their function. In this case, "markdown". In the case of Gemini, "duplicates", etc.
