Google Desktop Search
GDSearch (Google Desktip Search) is an alternative File search plug-in for
Eclipse. Instead of using the default (and kind-of slow) File search
capabilities, this plug-in uses the Google Desktop Search Engine instead.
Usage
The search can be started from either the Search menu or the Google Desktop
Search Toolbar Action:
It can of course also be reached by using Ctrl-H like other Searches and
switch to the "Google Desktop" tab. This tab lets you enter in
the search term and which context to search for it. You can also speed up the
search by selecting just an extension to search for (like java, which is the
default extension).
