Fortunately, I keep my Macs "lean and clean", and thus do not need to do many searches for something.
I don't think the need to do searches has anything to do with streamlining. After 31 years of using computers I still have only 187 GB used, including all system and applications files. However, there are always several ways to file any particular document, the person, their organization, the activity, et cetera.
It's like the old days of paper filing.."Where did I file that?" Digital searching just makes everything easier.
