I have a web site which is maintained by CMS (Content Managment
System). This system allows users publish one item of content to
multiple locations on this web site. Swish-e search returns every
instance of this one content item and for end user it seems that results
are duplicated. Each item shares the same content id. Is it possible to
"filter" my results by this id and remove the duplicates.

Thanks
