Hi, I tried asking this over on the ยต forums with no luck, so I thought maybe I would ask over here before moving on to wp-hackers for some insight.
I've been scouring google to try and find out if this is possible, along with the codebase, but I'm coming up at dead ends.
I know it's possible to restrict your WP search to specific categories. Nice feature, but I was wondering if you could go one further and restrict it to a specific page, and preferably its children.
Update: Seems running page_id, p or pagename in the query string all either return a 404, or redirect you to the page itself. So I'm wondering if you can hook the_posts and just modify WP_Query there...
Update: ahh I was hoping it'd be as simple as modifying page_id in the query vars to the appropriate ID, but no go there either.
