The command VxOccur from the script 2606 will run grep and turn the
above list into something like:
filename
21: This is a context line
22: This line contains STRING
23: This is another context line
filename 2
...
It will display the matches in a popup window. Then you can use the
filter mode (press f) to narrow the results interactively. If you
search for 'STR' you would see:
filename
22: This line contains STRING

In the new (unpublished) version the 'STR' in STRING would also be
highlighted.

You have to set g:vxoccur_grep_mode to 1 or 2 if you want to use grep
(0 uses :vimgrep).
For grep to display N context lines, add -CN to the range of files to
search when prompted.

VxOccur documentation:
http://vimuiex.sourceforge.net/vimdoc/vimuiex_plugins.html#vimuiex-vxoccur
The script

The preview of the next version:
http://sourceforge.net/projects/vimuiex/files/tar/vim-7.3-226-puls-vimuiex-0.8.tar.bz2/download
This implements the popuplist() function in C. Different algorithms
are implemented for filtering the displayed items. They are described
in help, see :h puls-matchers, or the file runtime/doc/popuplist.txt
in the tar file.
