The search uses the same image recognition skills that Google Photos had for some time. For eg. If the users search for guns, they might also see images of wars and violence. This is really an interesting search feature rolled out by Google, however it is unsure how many emoji it is going to support.
Google has taken searching algorithm to the next level, as it is now allowing users to search using any emoji icon. Google stated “An emoji is worth a thousand words”. This feature may be highly appreciated by lazy Google users, as they now they don’t need to type a complete line instead you just need to use an emoji for searching images.
