How to override normal WordPress search in Buddypress?

hi
i have wordpress and buddypress installed and i wanted to be able to search through forum posts, blog posts and other info all over the site.

i found Search Engine (WordPress Plugin) and installed it.
after a brief indexing process i was able to perform all of my search requests but the problem is that when this plugin is enabled and i try to search for something inside the wp-admin, there are no results. when i turn the plguin off the wp-admin search runs.
i also tried google search plugin but the outcome was the same.
how can i keep my search plugin and the normal plugin work together?
thanks
