Once the criteria for the main search has been entered and the report generated, there is a facility to focus this further by adding additional criteria via the ‘refine search’ option.

It is possible to search for articles by keyword, year of publication, first author, and title. These can be used separately or in combination. When using the keyword functionality this is across the whole database including title, author, and abstract. To focus the search, it is recommended that you place several keywords into this field.
