As far as I know, the search window tab depend of the open file you're on when calling the search function. So, for example if your on a web.xml file, it will open the "plug-in search" instead of the "java-search".
Edit: there is a way to force the default open tab, by assigning a shortcut to the "File Search" action in the "Keys" preference panel.
