This is a coding challenge of a different sort. Take this XML export of Rosetta Code's task pages, and create a mashup with the data. Post a link to your mashup in the comments below. If you don't have convenient hosting for it, leave a note in the comments and someone will give you a hand, if possible.If production of your mashup is/can be automated, please make a note of it; Regular exports of RC data are on the to-do list, and it would be pretty slick if interesting mashups could be generated in sync.Be aware that the exported data linked to above is licensed under version 1.2 of the GNU Free Documentation License.

Since the rosettacode search feature is disabled, i made a mashup that searches all the code snippets.
The index was created using AutoHotkey, and the user interface is in javascript.
Source for the indexing code is on github:

For now, only single word searches are supported.
Enjoy :-)

I'm not sure what it is that you are looking for, but I created a quick-and-dirty little application playing with your data, created in AutoHotkey:
