Or do you mean queries forwarded by home assistants trying to parse inputs?
The calling card of the developer realising that real users never act like you expect :)
As a developer, I search using keywords; for example, if I was looking for property for sale in Inverness, I might search for "property Inverness", whereas I've seen and heard "typical" users use something like "find me a 2 bedroom house with a garden for sale in the North of Inverness" - much more verbose, and containing stop words and phrases unlikely to help (I think!).
So did I.
Around the time I left Google behind I had started to search like my wife did, using full sentences. it sometimes worked better I think.
Natural language is likely the preferred search input method for kids under a certain age, who cannot yet type fluently. My kids formulate very long, complex queries verbally. The other day my son asked Alexa why the machine gun is such a deadly weapon. She replied with a snippet from Wikipedia that was surprisingly relevant.
