You can access publications by subject by pressing the Subjects button. This brings up a list of subjects, represented by bookshelves. Click on the bookshelf icon of a subject heading to display the sub-headings, or to return to the main subjects. Click on the icon of a sub-heading to obtain the concerned documents.

You can access publications by title by pressing the Titles button. This brings up a list of books in alphabetic order. To display a list of documents starting with a character (e.g. A) click on the corresponding letter.

You can access publications by organization by pressing the Organizations button. This brings up a list of organizations. Select the icon of an organization to view the concerned documents.

You can access publications by keyphrase by pressing the Index button. This brings up a list of keyphrases in alphabetical order. Click on any keyphrase to view the alphabetical list of publications containing the selected keyphrase. To get the list of titles containing the keyphrase, select the keyphrase in this page, uncheck the "text" box in the Search page, and press "Search".

How to search for particular words

From the search page, you make a query in these simple steps:

  1. Specify what items you want to search
  2. Say whether you want to search for all or just some of the words
  3. Type in the words you want to search for
  4. Click the Search button

When you make a query, the titles of 50 matching documents will be shown. There is a button at the end to take you on to the next 50 documents. From there you will find buttons to take you on to the third 50 or back to the first 50, and so on. Click the title of any document, or the little button beside it, to see it.

By default the search returns all the matching results. You can change this option by clicking the Preferences at the top of the page.

Search terms

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 cannot search for words that include punctuation.

For example, the query

Agro-forestry in the Pacific Islands: Systems for Sustainability (1993)

will be treated the same as

Agro forestry in the Pacific Islands Systems for Sustainability 1993

Search options
  • Use Boolean operators: AND, OR, NOT, NEAR
    • Use AND between words to retrieve text containing both words
    • Use OR between words to retrieve text containing either word
    • NOT retrieves text that does not contain the word following it
    • NEAR is used to specify the maximum distance apart (x) two query terms must be for a document to match. When selecting the NEAR operator the Choose desired proximity box pops up showing x = 4. You can replace 4 with another number in order to change the maximum distance between the two query terms. Near by itself defaults to 20.

Query type

There are two different kinds of query.

  • Queries for all of the words. These look for documents (or chapters, or titles) that contain all the words you have specified. Documents that satisfy the query are displayed, in alphabetical order.

  • Queries for some of the words. Just list some terms that are likely to appear in the documents you are looking for. Documents are displayed in order of how closely they match the query. When determining the degree of match,

    • the more search terms a document contains, the closer it matches;
    • rare terms are more important than common ones;
    • short documents match better than long ones.

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.

Scope of queries

In most collections you can choose different indexes to search. For example, there might be author or title indexes. Or there might be chapter or paragraph indexes. Generally, the full matching document is returned regardless of which index you search.

If documents are books, they will be opened at the appropriate place.

Change preferences

On the Help page, there are two pairs of buttons that control the case differences and word endings of your queries. The first set of buttons controls whether upper and lower case must match (case differences). The second set controls whether to ignore word endings or not (word endings).

For example, if the buttons ignore case differences and ignore word endings are selected, the query

African building

will be treated the same as

africa builds

because the uppercase letter in "African" will be transformed to lowercase, and the suffixes "n" and "ing" will be removed from "African" and "building" respectively (also, "s" would be removed from "builds").

Finally, you can control the number of hits returned, and the number presented on each screenful.

5 useful tips to get started in five minutes

1. You can search publications in this library by typing words to search, by subjects, by titles, by organizations, by keyphrases and by keywords.

2. Searching for some words displays the titles by nearest hits.

3. Searching for all words displays the results alphabetically by titles. This is the default search. To view matches starting with "Z" set your preferences to display the maximum number of hits.

4. Use "quotation marks" to search for exact matches of words.

5. Set your preferences to suit your needs. The number of total hits displayed can be set up to 50.000 or more, with 10 to 500 hits per page. The "ignores word endings" setting augments the number of hits. You can change the preferences to uppercase / lowercase sensitivity if needed.
