The keywords used to index the news items come from:
- the "keywords" field in the feed submission form: all items inherit the keywords assigned to their source feed;
- the and elements assigned to the items themselves in the source feed.
Therefore, the reliability of the keyword search depends on the quality of the source feeds.
Complying with the following general rules will help to offer a better service:
- Assign different keywords to different and instances (these elements are repeatable)
- Use a controlled vocabulary for selecting the keywords (Agrovoc recommended)
