Feature Request - Global Site Search needs to be more POWERFUL

Hi

I may have mentioned this before,

Global site search only searches posts, as post indexer only indexes posts.

And, it only indexes posts that were created AFTER indexer was installed.

And, it does not search any buddypress content.

1) Can a script please be made so that indexer would actually see posts prior to indexer being installed?

2) Can this script also handle custom post types and buddypress content?

Any +1s?

Many thanks,

Johnny
