suggesting new functions


First, I would like to thank you for this great tool, I am familiar with some of the commercial search engines for source codes and I liked your tool that looks just like slickrun which is a tool that I have been using for a while.
I have few suggestions:
1-support more programming languages.
2-implement cross-referencing and hyperlinking ( code need to be displayed in HTML, methods calls should have links to their implementation, in another words, if you click on a method you can go to the method implementation.
3-show code in colors just like in Visual Studio.
4-Allow searching for any word in the source code not just methods/types names (I am not sure if this is already implemented)
5- I noticed that indexing step, is slow. I don't think Lucene engine is the problem. I need to see the code and check this.
