One possibility is that you need to declare the type for tag_ids as :multi because TS can get confused (I just discovered this here http://groups.google.com/group/thinking-sphinx/browse_thread/thread/9bd4572398f35712/14d4c1503f5959a9?lnk=gst&q=yanowitz#14d4c1503f5959a9).

But why not use the tag names to search? E.g.,

Announcement.search params[:announcement][:search].to_s, :conditions => {:tags => "my_tag"}, :page => params[:page], :per_page => 10

Or, if you need to search for multiple tags:

Announcement.search( "#{params[:announcement][:search].to_s} (@tags my_tag | @tags your_tag)", :page => params[:page], :per_page => 10 )

(as aside, you may want to sanitize/remove sphinx-control-characters from the user-provided query before using it).

For debugging, I would go into console and strip down your query as much as possible (eliminate pagination arguments, even the query (just do ""), etc.).
