In eclipse, when i do a global search (open search dialog), i can get a list of results.
However, when i open these results, eclipse will ever only open one file at a time. That is, given results:
A
B
C
i can double-click on A and will see that file. However, if i then double-click on B, file A will be closed, and replaced by B
I'd like to be able to read both files (or as many files as i care to double-click on)... how can i do this?
Go to Preferences > General > Search
Unselect the box marked "Reuse editors to show matches"
Click Ok.
That should do it.

When I use the File Search option in Eclipse, when I get multiple results and I'm not sure about which file is the one I am looking for, I open a couple of them. However, File Search option "shares" the same tab and when opening the second file, it replaces the file that was opened first.
Is there a way to prevent this behaviour and get each file to open in its own tab?
In 'Preferences' go to the 'General > Search' page.
The 'Reuse editors to show matches' option controls using a single / multiple editors for search results.
I clicked something or accidentally drug a file that was open in the editor and now it is no longer displayed.
If I double click on the file in Package Explorer it doesn't show in the editor like it used to. I have looked all over and can't figure out how to get this file back in the editor.
I thought clicking File - Open File would do it but that displays an open file dialog.
Another way to simulate this is to put the cursor in the editor for an open file and select File - Close. This closes the file but then if you double click on the file in the Package Explorer it doesn't open it in the editor anymore. How do I get these files to display in the editor again?
I also tried right clicking on the file and selecting "Open". This does not display in editor either.
I also tried right clicking and selecting "Open With Java Editor". This does not work either.
If I clicke "File" and then the name of the file in the MRU list . This does not work either.
Also, double clicking a file in Package Explorer fails to open any file. The file shows in the File MRU list but does not display in editor. Can not figure this out.
Also, if I select "Back to" or "Forward to" arrows on toolbar, it tracks the file in the Package Explorer by highlighting it but the file does not display in an editor like it used to.
Also, I have tried "File Open" browsing to the physical location and selecting it but that does not display in the editor either.
I had to open a new window (Window - New Window) and then Reset Perspective (Window - Reset Perspective) to get the editor back. Not sure why but I lost some of my perspective settings doing this.
In Package Explorer, instead of double-clicking on the file, try to right-click it and you should get several "Open with..." options; choose the one that matches the editor in which you want the file to open.
Your choice will also be saved as the default, so the next times you can just double-click and it will open in that same editor.
If you are customizing the perspective, then saving perspective could be a safer option to avoid such glitches.

I would like that each time I open a reference to another file, Eclipse will be forced to open the file in a different editor, even if the current editor has already a tab with that file.
The motivation is that I hate when I click CTRL+Left Click (or just F3) to open a reference to a variable/function/class and such... it uses my current editor to open the file, drives me nuts because I have 6 different editors open in my workspace, and I would highly like them to be utilized.
An image for illustration, in this image Eclipse is open with 4 different editors.
Any ideas?
To me it sounds like this is what you like to do:
Eclipse: Files opened by multiple searches using same editor tab
"Disable the option
Preferences > General > Search > Reuse editors to show matches"
Although this will not open a second tab for an already opened file.
Sounds like you might have limited the number of open editors in your preferences, causing them to be recycled.
How do I compare two files using Eclipse?
(Currently I am using WinMerge.)
To compare two files in Eclipse, first select them in the Project Explorer / Package Explorer / Navigator with control-click. Now right-click on one of the files, and the following context menu will appear. Select Compare With / Each Other.
Just select all of the files you want to compare, then open the context menu (Right-Click on the file) and choose Compare With, Then select each other..
If one or both of the files you wish to compare isn't in an Eclipse project:
Open the Quick Access search box
Linux/Windows: Ctrl+3
Mac: ⌘+3
Type compare and select Compare With Other Resource
Select the files to compare → OK
You can also create a keyboard shortcut for Compare With Other Resource by going to Window → Preferences → General → Keys
Other than using the Navigator/Proj Explorer and choosing files and doing 'Compare With'->'Each other'... I prefer opening both files in Eclipse and using 'Compare With'->'Opened Editor'->(pick the opened tab)...
You can get this feature via the AnyEdit eclipse plugin located here (you can use Install Software via Eclipse->Help->Install New Software screen):
http://andrei.gmxhome.de/eclipse/
If your compairing javascript you might find it not displaying.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=509820
Here is a workround...
Window > Preferences > Compare/Patch > General Tab
Deselect checkbox next to "Open structure compare automatically"
Compare with Other Resource – The Easy Way using Eclipse (no additional plugin required)
To assign a keyboard shortcut to the feature, go to Window > Preferences > General > Keys, look for the command Compare with Other Resource and assign it to a keyboard shortcut of your liking. See How to manage keyboard shortcuts in Eclipse for more details on configuring shortcuts.
Tip: Alternatively, you could press Ctrl+3 (for Quick Access) and search for Compare with Other Resource. This way you don’t have to configure a shortcut but you’ll have to search for the command every time in Quick Access.
Once the shortcut is assigned, you need to select the source file from the Package Explorer, Project Explorer or Navigator. The easiest way to do this from an open editor is to assign a shortcut to instantly show the file in the Package Explorer or, if it’s not open, to open it quickly using the keyboard.
Now press the keyboard shortcut you assigned to Compare with Other Resource and the following (non-modal) dialog should appear:
Troubleshooting: If the dialog doesn’t appear, it’s probably because you haven’t selected a file in either the Package Explorer or another view that allows file selection. Make sure a file is selected and make sure you haven’t selected the class in the Package Explorer rather than the actual Java file.
Now you can select the second file in the Package Explorer and drag and drop it onto the dialog. Click OK and the comparison editor should display, comparing the two selected files.
Tip: See the post on using shortcuts for common SVN commands for tips on how to navigate the comparison editor with the keyboard.
Comparing External Files
Using the Compare with Other Resource dialog, you can compare a workspace file with an external file or even compare two external files with each other.
Comparing a workspace file with an external file is easy: Once you’ve opened the dialog from a selected file, instead of dragging and dropping another workspace file, tick External File in the Right pane and then Browse to a file on your filesystem.
To compare two external files, you have to start the dialog again from a selected workspace file (choose an arbitrary file). Once open, select External File in the Left pane and Browse to your file then do the same for the Right pane.

If you have Beyond Compare installed, the ContextQuickie eclipse plugin has an option to enable it to be selected from the context menu displayed when you right-click a file.
Install from:
https://github.com/ContextQuickie/ContextQuickie/wiki/Installation
After install, activate Beyond Compare menu items via Window->Preferences->Context Quickie->check 'Enable Beyond Compare'.
When using the "file search" function in eclipse to find a bit of text in a ".java" file, I may get a list of several search results. Let's say I double click on the file "A.java" which then opens A.java in a new editor tab. If I then use the "file search" function again to find some other bit of text and this time double click on the file "B.java", this file will replace "A.java" in the editor.
I'd like Eclipse to open a new editor for B.java so that both A.java and B.java are available in my editor tabs. Is this possible? I've had a look around in the preferences but I'm not sure what option would give me this bit of functionality.
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
