Documentation/sysctl/vm.txt is linux source tree explains swappiness:
719 This control is used to define how aggressive the kernel will swap
720 memory pages. Higher values will increase agressiveness, lower values
721 decrease the amount of swap. A value of 0 instructs the kernel not to
722 initiate swap until the amount of free and file-backed pages is less
723 than the high water mark in a zone.
725 The default value is 60.
It's easy to find docs on other parameters just by grepping.
