--- Comment #3 from Jared Camins-Esakov <jcamins at cpbibliography.com> ---
Part 1. Basic description.
Although Koha has had the option to sort search results by “popularity” for
years, the feature was never fully implemented. A working popularity sort would
allow patrons (and staff) to view their search results sorted according to
which items are most popular. In order to implement this feature 942$0 (total
issues) will need to be automatically updated when items are checked out, and
the indexing configuration adjusted slightly to take advantage of popularity
data.

Part 2. Additional features.
Several additional changes are required to take advantage of the improved
popularity support:
* A system preference is required to allow users to disable the automatic
popularity index update
* The DOM indexing configuration should be set up so that popularity can
automatically be computed by summing the number of times each item was issued
(this will be done on a separate bug report, since the DOM indexing
configuration is dependent on bug 7818, and the rest of the work on this bug is
not)
* A script to populate field 942$0 with historical data is needed, since Koha
has not been keeping 942$0 up to date
