How to search for particular words
From the search page, you make a query in these simple steps:
- Specify what items 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.

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.

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.

_textdatesearch_
Date search lets you find documents that, as well as matching your search
terms, are about events within a certain timeframe. You can search for
documents from a certain year or from a range of years. Note that you do not
have to have any search terms -- you can search by date alone; and also that
you do not have to use dates in your search, if you do not type any dates in it
is just the same as if the date search didn't exist.How to use this feature:
The way results of your search work
Generally speaking a search for documents about the year 1903 will not return documents that, say, reference books written in 1903, just documents about 1903. However, the way that the documents' dates are found, it will return documents that have a date range (for example 1899-1911) that includes 1903, and also those documents which, as part of their text name the century that 1903 is a part of (for example 20th century or twentieth century). This means that for some documents, the dates in your search will not actually appear in the document text. For a range search, all of this applies to every date in the range._textchangeprefs_
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.
Language preferences
Each collection has a default presentation language, but you can switch to
a different language if you like. You can also alter the encoding scheme
used by Greenstone for output to the browser -- the software chooses
sensible defaults, but with some browsers better visual results can be used
by switching to a different encoding scheme. All collections allow you to
switch from the standard graphical interface format to a textual one. This
is particularly useful for visually impaired users who use large screen
fonts or speech synthesizers for output.
Presentation preferences
Depending on the particular collection, there may be several options you can
set that control the presentation.
