I would like to remove these other options to search across only blogs where I'm a member, pages v posts, etc, and just have a search across all blogs, all content types (including a custom post type 'documents' if possible).
I'm fine hacking up the plugin if I need to. I'm fine changing form elements to hidden ones, which I've already done in fact. The biggest thing hanging me up right now is how to return both pages and posts.
Any help would be much appreciated, thanks.
