is a simple web interface to the Library Catalogue. The Catalogue is
a list of books and technical reports grew out of the collections
built up by the libraries. Troodon, an information retrieval module
operating in the web environment, lets you search for terms of your
choice throughout the database of libraries holdings. A database is
an organized collection of " records ". Each "record"
represents a book, conference proceedings, report, etc. Records are
sub-divided into categories of information known as "Fields",
such as title, author, edition, etc.
your browser's BACK button to return to the Search Form to refine
your search and make adjustments if the initial results are not
will look for items that satisfy all of the elements you supply,
e.g, if you fill in an author name and a title word, Troodon will
only find items that contain both that author name and that title
word. In most cases a simple Title word/phrase search will be
initial response to a successful search is title list of the first
twenty items. You can display the next twenty titles at a time by
clicking on the "Next" button, or display the
bibliographic details about an individual item by clicking on its
item number which appears to the left hand side of the description
is case insensitive—It makes no difference whether you
type all in upper case, all in lower case, or a mixture of the two.
typing a search term, eliminate all punctuation, such as period,
comma, apostrophe, etc, as these are treated as equivalent to space.
For example, On line, not
s disease, not parkinson’s
disease and G E Corp,
not G.E. Corp. The
catalogue database has a list of stop words that are not used for
Searching. Stop wards are usually common words that have no
significant meaning in a Search such as ‘of’, ‘as’,
‘there’ etc. If you use a stop word within a phrase,
Troodon will display zero result. For example, if ‘of’
is a stop word and you search for applications of mathematics,
Troodon will display zero record.
to separate keywords—Separate phrases or words by using a
comma. Troodon will treat a phrase as a complete phrase (words
appearing next to each other in the same order) but will treat words
separated by a comma as keywords, picking them up in any order from
the title fields of the item e.g. "information retrieval"
will look for the phrase "information retrieval" while
"information,retrieval" may pick up items called
"Information storage and retrieval". In brief, using the
comma is the same as using the Boolean AND feature, meaning that
both elements have to be found in the item for it to be a hit.
is possible to truncate a search term if you are not sure of its
complete form or spelling.
like 'OR', 'AND', 'NOT' can be used between words or phrases in the
same field and between fields.

accepts only numeric values. If search result is larger than what can
be accommodated in single page, you can view it page wise.

specified. This can be "AND" or "OR" boolean

criteria matches for each records. Boolean OR operator searches those
records where any one of the criteria matches for any records.
