Restore Search access to sub-forum and thread areas

Currently, the only search option is located at the very first level of the forum (Home). For a variety of reasons many people end up in the forum bypassing that level and are not even aware that there is a search function in the forum. It would facilitate accessing existing information as well as communication if a search field were available at the sub-forum (Boards) and thread levels. It has been available at these levels in the past.
