DSpace provides by default two types of browsing, naming them single browsing and full browsing according to the corresponding names of the .jsp files that are responsible for handling each request (single.jsp & full.jsp).
Each type of browsing is defined accordingly and configured in different way in the configuration file dspace.cfg.
The proposed improvement is applied for the case of browsing by a unique index of metadata values from the item (single browsing). In this case, the user can define for each metadata browse index whether he wishes to add next to its various metadata values the frequencies of items that are included. The configuration takes place in the dspace.cfg.
Attached you can find the patch file and a readme file with details about tha configuration that is needed to be made.
