If you have more than, let's say, 10 files, this plug-in is worthless. It will produce search results from your Phoca Download database, however from there you get dumped into a list of the entire category, it will not point/link to the exact file, so if you have a 100, or 1000's of files, the end-user has to search through each page to find the item they just queried. Worthless to an end-user.
I poured through the forums for a solution, if you can even get access to the forums without some prompt denying entrance because of spam.
When I was able to get into the forums, I discovered there were other forum posters with the same problem, and the moderator provided zero solution. Worthless plug-in, and difficult to get support. Very little documentation.
