'Filter by project' helps you discover content related to a specific project of interest.
By using a 'Filter by project' field (near top of overview pages), you can narrow down a list of articles related to a tag. Using this filter in effect provides a layered filtering: showing tagged content related to a specified project tag.
Specify in the 'Filter by project' field your term of interest (as you start typing, the field automatically tries to show you relevant tags) and then select 'Apply' to check for content tagged with your filter term.
As illustrated below, in some cases you may wish to combine filters. If you would like to find every 'event report' mentioning 'dublin core' as well as the organisation 'cetis' and the project 'iesr', for example, then you could activate four filters specifying article type, keyword, organisation, and project as in the example below.
