/**
 * Smart Search CLI.
 *
 * This is a command-line script to help with management of Smart Search.
 *
 * Called with no arguments: php finder_indexer.php
 *                           Performs an incremental update of the index using dynamic pausing.
 *
 * IMPORTANT NOTE:  since Joomla version 3.9.12 the default behavior of this script has changed.
 *                  If called with no arguments, the `--pause` argument is silently applied, in order to avoid the possibility of
 *                  stressing the server too much and making a site (or multiple sites, if on a shared environment) unresponsive.
 *                  If a pause is unwanted, just apply `--pause=0` to the command
 *
 * Called with --purge       php finder_indexer.php --purge
 *                           Purges and rebuilds the index (search filters are preserved).
 *
 * Called with --pause           `php finder_indexer.php --pause`
 *          or --pause=x         or `php finder_indexer.php --pause=x` where x = seconds.
 *          or --pause=division  or `php finder_indexer.php --pause=division` The default divisor is 5.
 *                               If another divisor is required, it can be set with --divisor=y, where
 *                               y is the integer divisor
 *
 *                               This will pause for x seconds between batches,
 *                               in order to give the server some time to catch up
 *                               if --pause is called without an assignment, it defaults to dynamic pausing
 *                               using the division method with a divisor of 5
 *                               (eg. 1 second pause for every 5 seconds of batch processing time)
 *
 * Called with --minproctime=x   Will set the minimum processing time of batches for a pause to occur. Defaults to 1
