Here's How You Can Download Entire Google Search History
Google recently made it possible to download your entire search history - everything you've ever searched for while you've been logged in is now available for you to look.
The feature was first noted by Google Operating System blog. To download the search history, browse to Google Web History, and click the gear button and select "Download."
"You can download all of your saved search history to see a list of the terms you've searched for. This gives you access to your data when and where you want," Google said. "When you download your past searches, a copy of your history will be saved securely to the Takeout folder in Google Drive. You can download the files to your computer if you want a copy on your computer."
Once you request to download the file, Google will send you an email 'with a link to that archive on Google Drive.
However, the feature might not work for you if opted out of the web history.
