Hi, author here.

Likely the most significant benefit is the more powerful query language. For example you can also search by file modification date or size and use boolean operators. https://github.com/cboxdoerfer/fsearch/wiki/Search-syntax

Ah thanks for that, I can see the benefit there alright.

For example it updates after every character you type. Sometimes you don't know exactly what you are looking for or you are exploring.
