Ordering
Basic ordering capabilities are available in the package module server.
They rely on the data model attributes:
sort_ranksort_desc
Defining the ordering of the items is done from the admin console (in the data model section):

It is done with the attribute wizard (when creating or updating an attribute).
sort_rankdefines in which order the attributes are used to sort the itemssort_descis whether an attribute should be used in descending order
Note
The ordering is applied at the main filtering layer level.
