Eclipse: Files opened by multiple searches using same editor tab
Disable the option
Preferences > General > Search > Reuse editors to show matches
Above is the best answer. But since I don't always want to open the search result in a new tab I usually use something like this.
right click on the result -> Show In -> Package Explorer ->(file is now automatically selected)->Press 'Enter'
More simply
Select the result -> alt + shift + w -> Package Explorer -> press 'Enter' twice
