Previously, search options in Google Search were displayed
using the following configuration:
Web -- Shopping -- Images -- Videos -- News -- More -- (+Search Tools)
Google have released a silent terminology update, changing the
term “Web” to “All”:
All -- Images -- Shopping -- Videos -- News -- More -- (+Search Tools)
This update affected Google's search engines in all languages worldwide, and apparently took place because "Web" results commonly displayed other elements such as news, videos, pictures etc. rather than showing website results alone.
Beyond this terminology change, no other changes were observed.
