BuddyPress.org

Hello,
I would like to ask for some starting point on how to handle my needs. I want to make a Custom search for Groups, Each group in my wp_db_groups table have additional column called, let’s say, colour ( It’s a bit more complex in fact and I can not store it in meta due to a performance issues ) and I need to make a custom query and display somehow the results based on colour that user posts from some form. I jumped into a great tutorial here ( http://buddydev.com/buddypress/buddypress-globalsitewide-unified-search-update-for-buddypress-1-5/ ) but what I want is to leave the original search intact and just make an additional… component? Well, I discovered then BuddyPress Skeleton Component, but it seems too complex for me right now. As I will try to analyze it can someone in the meantime explaint to me basic steps how to perform such task? That is: handle the form request and display the results from the database. I would like to see something like this: http://example.com/custom-search/?colour=blue&second-colour=red and display resluts based on those two parameters.

Thanks in advance
Cheers

//EDIT
I found this topic: http://buddypress.org/community/groups/how-to-and-troubleshooting/forum/topic/make-your-own-custom-buddypress-page/
but it doesn’t work, probably because code posted there is three years old…
