Result Count
Sometimes, a query might produce too many answers
and you want to limit the number
of answers returned. You can do this by using the
count limit search control.
By default, a search does not have a count limit--it will return all answers that it finds.
To set the count limit of a search, pass the number
to
SearchControls.setCountLimit().
The following example
sets the count limit to 1.
// Set the search controls to limit the count to 1
SearchControls ctls = new SearchControls();
ctls.setCountLimit(1);
If the program attempts to get
more than the count limit number of results, then a
SizeLimitExceededException will be thrown.
So if a program has set a count limit, then it should either differentiate
this exception from other
NamingExceptions or keep track of the count limit and not request more
than that number of results.
Specifying a count limit for a search is one way of controlling the
resources (such as memory and network bandwidth) that your application
consumes. Other ways to control the resources consumed are
to narrow your
search filter
(be more specific about what you seek),
start your search in the appropriate context,
and use the appropriate scope.
