Location of search cache for SlskQT and Legacy Client on Win 64 bit

Can someone point me to the file name and location of the SoulseekQT and Legacy SLSK157 client's search CFG file on a windowss 8, 64-bit system?

When using Windows XP I was able to locate the search cache (CFG) file and was able to manually edit or clear it. I cannot seem to locate a way to clear the search cache otherwise.

I'd like to locate a way from within the client to clear the search list in both, but it appears that it is not a user option. Therefore, finding the file and editing it manually would be desirable.

Thank you.

To clear your search history in SoulseekQt, use the 'Clear Search History' button in the Options->General tab.

How do you do this on a mac? i can find any buttons to clear the history or any files to delete.
