Browsing
Browsing is a good way to access documents if you don't have a specific
idea of what you're looking for. There are two ways to browse the repository,
by subject and by year.
To browse the repository either select Browse from the front page or
from the navigation bar at the top of the screen. Then choose which property
you wish to browse by eg. "subject".
You will be presented with a list of possible values, select
one of these, and you will be given a list of references to documents in
the repository (if any) which match this value.
To access a paper, simply click on its reference in the display.
On the abstract page, you should be able to see what subjects are
pertinent to the current document. Clicking on one of those subjects will
take you back to the relevant browse by subject view.
Searching
The repository offers two levels of searching, simple and advanced. They
are similar, but the advanced form lets you perform a finer-grained search
using more fields. Access the simple search using the Search the Repository
link on the front page, or using the navigation bar at the top
of the screen. To perform an advanced search, use the advanced search link
at the top of the simple search page.
Text Search Fields
These are used to search fields like abstract or author. These are the
fields where there is a text entry area, and a popup menu just to the
right of it. Type your search terms into the box. You can decide how the
system will use your search terms by selecting one of the options from the
popup menu just to the right of the input box.
Match all, in any order. In the example shown, the system will search for records in which any
of the title, abstract or keywords fields contain both the word
``patient'' and ``care''. Match any. In the example shown, the system will search for any record with either
the term ``patient'' or ``care,'' in any of the title, abstract or
keywords fields. Match as a phrase. In this case, the system will search for your terms appearing exactly
as you type them. In the example, the system will return any record with
the phrase ``patient care'' appearing in the title, abstract or
keywords.
Lists of Values
With these you can select one or more values from a list of values for
the system to search for. If no value in the list is selected, the system
will ignore this field (i.e. it will
retrieve records with any value of this field.)
In cases where each individual record may have more than one value
attached to the list, you can also change search behaviour by selecting
``Any of these'' or ``All of these'' from the popup menu on the right of
the list.
Any of these. If this is selected, any record which has any of the values you select
will be retrieved. All of these. If you select this option, a record must have all the values you choose
associated with it to be retrieved.
Years
When you're searching a year field, you can specify a single year or
range of years that you're interested in:
- 1999
- retrieves only records where the year is `1999';
- 1987-1990
- retrieves records with years between 1987 and 1990 inclusive;
- 1995-
- retrieves records with years of 1995 or later;
- -1998
- retrieves records with years up to and including 1998.
Yes/No Fields
Some fields can have the value yes or no, for example the ``Refereed''
field. In this case, the search field lets you specify whether you want
retrieved records to have the value yes or no for this field, or whether
you have no preference, in which case the field isn't used to find
records.
