KM search functionalities
I'm searching for a way to have the following features available for the Advanced Search in my portal:
1) I want to have a filter for special mime types (e.g. *.doc, *.pdf and so on)
2) I'd like to be able to search only for a special time period (e.g. the last two weeks)
3) The possibility that the search is only performed for filenames, not a full text search.
Is it possible to achieve these goals by cusomizing the KM search iview and the search options? Or do I have to write my own search component. If so, I found one good [documetation|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/41cbcb56-0701-0010-43b4-fbc138ea2b6a] by Thio Brandt. Is there some more information available?
Thanks a lot in advance.
