This restricts the number of concepts that can be included in a search, and reduces the number of alternate terms that can be used to search for a concept. Another issue is the lack of the Boolean OR and AND operators. The OR operator enables several terms for the same concept to be included in the search. The AND operator enables several concepts to be combined. NZ Explorer appears to have none apart from the text on the search screen, and the search capabilities have to worked out by trial and error.

The results of this study indicate that searchers for information relating to Australia and New Zealand need to search both local and global databases, and need to use more than one search engine. This survey did not examine specialised search engines that index websites selectively in their topic area.
