Until the advent of the CSH system, there was no problem with the search facility searching the whole site. Now we have the CSH documentation it makes sense to be able to search just the CSH text. However, adding the advanced search facility means that there is an extra box and thus the search block occupies more space. Rather than making the top line bigger, it would be better to mover the search box to the header area and make the top line smaller. See http://www.openvpms.org/forum/csh-only-search-facility#comment-8205 for a mockup of the adjusted theme.
