How it works: This database is created and maintained by an automatic program (spider) written by Paul Bourke. specifically for the NZ WWW environment. NZExplorer randomly selects HTML pages for exploration, these pages are analysed as follows:Any embedded links are extracted for later exploration as long as the link points to an HTML document and it resides on a server within the ".nz" domain. A set of keywords are extracted from the page and stored. The keywords consist of the first N unique words of the page after the HTML control language and punctuation has been stripped away.

NexTrieve text retrieval provides "fault-tolerant" ("fuzzy") searching. This approach improves searching by eliminating much of the trial and error present in exact searching. An example could be that of a foreigner searching for the Dutch actress "Soutendijk" by entering "Soendijk" becauses that's sort of what they could remember.
In most cases a straight forward, intuitive approach to searching will yield very good results with NexTrieve. In some cases however, a little insight can improve your search results.
NexTrieve will always attempt to find the closest match to your input query. This may on occasion result in a somewhat confused result if your query bears little resemblance to anything in the database. This is usually the result of entering too long a query.
Unlike other engines, NexTrieve applies the fuzzy matching to the entire query, and can be thought of as "fuzzy phrase retrieval". If several words are entered, none of which occur together the result can be diffused. In this case try just one of two words, or different words.
How to use: Enter any keyword(s) you wish to search for, separated
by spaces in the first search field. Any company/organisation whose name,
description, locations or categories contain one or more of these words
will be displayed in the search results.
Note: That entering locations as keywords
will work, however a company with "Wellington" in its name or
description that is actually located in Auckland, will be matched for the
keyword "wellington". To avoid this situation use the location
keywords field.
Search Locations You can use the location keywords field to limit
your search to companies or organisations which are located in certain
areas. Enter any location(s) you wish to search for, separated by spaces.
Any company/organisation which is listed under one or more of these locations,
will be displayed in the search results.
A location may be a town, city, region or island. Entering a location without
any other search keywords will return all the companies/organisations in
this location.
A clickable map of New Zealand is also available for overseas visitors who are unfamiliar with New Zealand geography.
Partial Matches: The default rule for matching a word, is to
include any word that contains at least the first part of the keyword.
For example : "inter" matches "internet", "international"
and "interesting"
To match only whole words put a "." after the keyword. For example
: "art." matches "Art" but not "Artistic"
Logic: The default logic rule for multiple keywords/locations is the "OR" rule. So : "computers books" is equivalent to "computers or books". You can use the keywords "or" and "and" and brackets to override this rule. For example : "computers and hamilton" "computers and ( hamilton or tauranga )" "( limited. or ltd. ) and internet"
Search Results: To help you manage the results of your search, a summary of the results by category or location is returned first. After this summary the first 10 matches are listed with an option for more. The summary section of the results enables you to select a sub category or location and view only those results from your search. You can also redefine your search at this stage by modifying your search keywords. This allows you to narrow your search further using "and", or expand it using "or".
