I said specific type of semaphore implementation in Java. I said 'hey, have you tried to find it using Krugle?' He fired up the 'hey, have you tried to find it using Krugle?' He fired up the page, entered his search details and was faced with several page, entered his search details and was faced with several pages worth of results, something traditional search had pages worth of results, something traditional search had failed to do.
