The Main Site Searches above are provided by Freefind which has Simple and Advanced Search Facilities. The FreeFind service is currently being optimised for our use but it does seem to work better than the previous version by Atomz and now indexes PDFs
Google also provides a Site Search facility based on their Web Search Engine. I have provided alternative searches of our Main and Uniquely New Zealand sites by Google. They are not likely to be as fully 'spidered' (indexed) as the Freefind options but the results currently display better on mobile devices.
