Guidelines for searching

Choosing a database
You must define the topic (keywords and synonyms) and choose a relevant database before starting the search.

Truncated search
Truncation means cutting off the end of a word when creating a search expression. The hit list will include all possible endings to the word, in addition to the root word itself. The truncation expression varies, depending on the database you are using. In general, only right-truncation is possible, i.e. end variations of words.
Example:
librar? will result in hits for all references containing "library", "libraries", "librarian", etc.

Boolean searching
The Boolean (or: "logical") operators AND, OR, and NOT help expand or narrow the scope of your search.
Example:
horses AND cattle: returns all documents with both words in them.
horses OR cattle: returns all documents containing either "horses" or "cattle" or both.
horses AND cattle NOT pigs: returns all documents with both "horses" and "cattle" in them, but omitting those documents containing "pigs".

Word and phrase searching
Depending on whether or not you know the exact title of the document you are looking for, you can search for either single (key) words, or a complete expression (phrase).

Characters
It usually doesnt matter if you use UPPER or lower case characters. The Norwegian characters Æ,Ø and Å, cannot be used in international databases.
Example:
= ae,a,e
= o,oe
= a, aa

Help
Every database has a number of help files and guidelines. Please refer to these, they often include helpful tips to make your searching more efficient.

Access to articles
Once you have found an article click the oria.no-button (not all databases have this button). Then you will see whether we have access to fulltext, if not, how to order a copy.
