In what order are the results displayed when I do a Keyword Search?

The system uses logic based on relevance to the entered search expression to provide the most relevant titles first.

Keyword search results are usually grouped by relevance to bring the most likely titles to the top of the list. Each group represents a similar level of relevance and results are sorted within the group by date or title. To get an ungrouped result set, use boolean operators to form a complex query.
Most relevant Most relevant titles
Highly relevant Highly relevant titles
Very relevant Very relevant titles
Relevant Relevant titles
Other relevant Other relevant titles
