I want to search only file in my system (no list entry etc).. I tried with "IdDocument" property setted to 1 in the search.
This works but not for every filetype. For example for .png file (after added in the option that i want sharepoint to search also in png files) if I search "IsDocument:true" I can't find it else I successed in.
Is there a place where I can set what is a document to me? Something like a file extension list where to put all image type?
Is any other hidden properties that tolds me if the element is a file or a list entry?
Thank you very much
