SphinxClient::setRetries — Set retry count and delay
$count
   [, int $delay = 0
  ] )Sets distributed retry count and delay.
   On temporary failures searchd will attempt up to
   count retries per agent.
   delay is the delay between the retries, 
   in milliseconds. Retries are disabled by default. 
   Note that this call will not make the API itself retry
   on temporary failure; it only tells searchd to do so.
  
count
     Number of retries.
delay
     Delay between retries, in milliseconds.
   Returns TRUE on success or FALSE on failure.
