Before you can run the SiteSearch indexer, you need to add it as a task to Scheduler app's task list. To do this, copy the task from the SiteSearch install folder into the proper place, like this:

$ cd /PATH/TO/SITELLITE
$ cp -R inc/app/sitesearch/install/sitesearch inc/app/scheduler/tasks/

The SiteSearch indexer will then be run as part of the Scheduler's task list. To execute it separately, you can use the following commands:

$ cd /PATH/TO/SITELLITE
$ php -f index scheduler-app sitesearch

This will automatically index all of the collections defined in your web site that specify a sitesearch_url property in their definition files (see inc/app/cms/conf/collections for examples).
