Using google search in my Chrome 94 ( kubuntu 20.04 ) I wonder if there is a way
to set parameter “Search for last year” as default when I open google search page?
Do you want the time frame for the search to be Past Year?
Go to Settings > Search engine > Click the “Add” button > Give it a Name and Keyword and use the string
https://www.google.com/search?q=%s&tbs=qdr:y for the Query URL > Find the new entry in the “Other search engines” list and click the three vertical dots next to it then select “Make default”.
