How to search for particular words
From the search page, you make a query in these simple steps:
- Specify what documents you want to search
- Say whether you want to search for all or just some of the words
- Type in the words you want to search for
- Click the Begin Search button
When you make a query, the titles of twenty matching documents will be shown. There is a button at the end to take you on to the next twenty documents. From there you will find buttons to take you on to the third twenty or back to the first twenty, and so on. Click the title of any document, or the little button beside it, to see it.
A maximum of 100 is imposed on the number of documents returned. You can change this number by clicking the preferences button at the top of the page.
_iconblankbar_
Whatever you type into the query box is interpreted as a list of words
called "search terms." Each term contains nothing but alphabetic characters
and digits. Terms are separated by white space. If any other characters such
as punctuation appear, they serve to separate terms just as though they were
spaces. And then they are ignored. You can't search for words that include
punctuation.
For example, the query
will be treated the same as
_iconblankbar_
There are two different kinds of query.
Use as many search terms as you like--a whole sentence, or even a
whole paragraph. If you specify only
one term, documents will be ordered by its frequency of occurrence.

Collection preferences
Some collections comprise several subcollections, which can be searched
independently or together, as one unit. If so, you can select which
subcollections to include in your searches on the Preferences page.
Presentation preferences
Depending on the particular collection, there may be several options you can
set that control the presentation.
Collections of Web pages allow you to suppress the Greenstone navigation bar at
the top of each document page, so that once you have done a search you land at
the exact Web page that matches without any Greenstone header. To do another
search you will have to use your browser's "back" button. These collections
also allow you to suppress Greenstone's warning message when you click a link
that takes you out of the digital library collection and on to the Web itself.
And in some Web collections you can control whether the links on the "Search
Results" page take you straight to the actual URL in question, rather than to
the digital library's copy of the page.
Collections that are capable of being presented in different languages allow
you to specify the interface language. If the language is Chinese, you can
also specify which of the standard Chinese encodings your browser uses.
Finally, all collections allow you to switch to a textual interface format
rather than the standard graphical one. This is particularly useful for
visually impaired users who use large screen fonts or speech synthesizers for
output.

There are several freely available technologies underlying the New Zealand Digital Library:
- Greenstone, the digital
library system that generates each and every page of this website.
- PreScript, a system
that converts PostScript to plain ASCII or HTML, detects paragraph boundaries,
removes hyphenation, and interprets many ligatures.
- MG, an enhancement of the Managing Gigabytes full-text
retrieval system, that provides flexible stemming methods, weighting terms,
term frequencies, merged indexes, machine independent indexes, and a port to
MSDOS.
- Sequitur, a
method for inferring compositional hierarchies from strings by detecting
repetition and factoring it out of the string by forming rules in a
grammar. The rules can be composed of non-terminals, giving rise to a
hierarchy. Sequitur is useful for recognizing lexical structure in strings,
and excels at very long sequences.
- Kea, a program for
automatically extracting keyphrases from the full text of documents. Candidate
keyphrases are identified using rudimentary lexical processing, features are
computed for each candidate, and machine learning is used to generate a
classifier that determines which candidates should be assigned as
keyphrases.
- Phrasier, a
tool to support information seeking activities in a digital library. Its novel design
reflects the fact that reading, writing, browsing and searching activities are rarely
carried out independently of each other. They overlap and interleave in ways which have
not been effectively supported by conventional information retrieval interfaces. Consequenly
Phrasier blurs the distinction between writing a document and finding material related to it;
between reading a document and finding others on the same or similar topics; between keyword
searching and subject browsing.
