Is this true anymore? It used to be true back when all the really cool Google search operators worked and the service didn’t use natural language processing to process search queries. But these days you’re ‘supposed’ to use google like this: ‘what is the purple wild flower that grows in spring in England?’ as opposed to ‘filetype:pdf site:blah.org +foo -bar 2010..2012’ which would find files of type pdf on domain blah.org referring to foo but not bar between the years 2010 and 2012. Honestly I prefer searching the latter way and would love to know which search operators still work these days.
