If you want to sort search results in your client application, then
make sure you have enough memory in the JVM to hold the results of the search,
and use one of the search methods that lets you pass in a collection of
SearchResultEntry
s. After the collection is populated with
the results, you can sort them.
If you are on good terms with your directory administrator, you can
perhaps use a server-side sort control. The server-side sort request control
asks the server to sort the results before returning them, and so is a
memory intensive operation on the directory server. You set up the control
using ServerSideSortRequestControl.newControl()
. You get
the control into your search by building a search request to pass to the
search method, using SearchRequest.addControl()
to attach
the control before passing in the request.
If your application needs to scroll through search results a page at a time, work with your directory administrator to set up the virtual list view indexes that facilitate scrolling through results.
