public class ConnectionControlSearcher extends Searcher
This searcher informs the client to close a persistent HTTP connection if the connection is older than the configured max lifetime. This is done by adding the "Connection" HTTP header with the value "Close" to the result.
The searcher reads the query property "connectioncontrol.maxlifetime", which is an integer number of seconds, to get the value for maximum connection lifetime. Setting it to zero will enforce connection close independently of the age of the connection. Typical usage would be as follows:

Searcher implementation subclasses will, depending on their type of logic, do one of the following:
Hits come in two kinds - concrete hits are actual content of the kind requested by the user, meta hits are hits which provides information about the collection of hits, on the query, the service and so on.
The query specifies a window into a larger result list that must be returned from the searcher through hits and offset; Searchers which returns list of hits in the top level in the result must return at least hits number of hits (or if impossible; all that are available), starting at the given offset. In addition, searchers are allowed to return any number of meta hits (although this number is expected to be low). For hits contained in nested hit groups, the concept of a window defined by hits and offset is not well defined and does not apply.
