Prototype: function SetConnectTimeout ( $timeout )
Sets the time allowed to spend connecting to the server before giving up.
Under some circumstances, the server can be delayed in responding, either
due to network delays, or a query backlog. In either instance, this allows
the client application programmer some degree of control over how their
program interacts with searchd when not available,
and can ensure that the client application does not fail due to exceeding
the script execution limits (especially in PHP).
In the event of a failure to connect, an appropriate error code should be returned back to the application in order for application-level error handling to advise the user.
