I just wanted to report and open up for discussion some plans I have for changes in the search engine concerning OR expression handling.  Emmanuel and I have had some IRC conversations about it but I want to document it and get feedback from others.  There's also some background information available that contrasts these optimizations in the documentation.  Here's a reference to it:

All ideas, thoughts or suggestions no matter how insane are appreciated :).

Thanks,
Alex
