How to leave the open file in eclipse tab after search?

when we open a file from "Package Explorer" in eclipse, after we use it, it will leave in the tabs.

If we open a file from "Search" result, then after we search another keyword, it will disappear, we need to see the search result to find out that.

Is there any solution that I can leave the opened tab in the tabs after I opened from Search panel ?

From main window, select Window - Preferences. On left, tree view, select General - Search. On the right, remove "Reuse editors to show matches". Click on OK button.

In Eclipse Kepler, if you double click on the found file (NOT THE FOUND TEXT) in the search, it will replace the file you double click to open previously. So to keep both files open, right click on the another found file in the search window and select open, this will retain the file you open previously.
