There is a WorkSite setting that limits the maximum number of items that appear when
viewing a folder and the number of returns from a search result. The default is 512 for
both items. If there are more than 512 documents in any folder, all documents will not be
visible when browsing through it.

To change this from FileSite:

  1. Go into the FileSite menu
  2. Select Options, then Advanced
  3. In the Server Settings, enter a larger value in the Folder return to a maximum of XXX documents

1000 is the suggested maximum setting.
