Oh, I was referring to today's typical Intel compatible processors. The OP was asking about how is search being performed with common PC hardware, so my comments were in that scope. But you are right, surely some custom string-searching hardware has probably been developed and made, it can probably be very useful in situations with specific need for that type of functionality. :-) Best, :-) Marko -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
