A bit more on relevance feature

I ve created a sample program today, which is a C# windows application, that can take a URL, go n fetch the page contents.

So by using a keyword search technique/algo on that html fetched content... we can add this feature, without the need do depend on external services of PHP. Will try something further for it.

Also 1 thing that occured to me, is that with every feature, we gotta keep in mind the limitations that we will currently have for that feature. like this relevance feature , and keyword search technique might not work for sites that have user authentication system before they reply.. so wil have to find ways around it, or set rules for it.
