How to enable "Search by Supervisor" in Theses only

[Snickers]

Dear All,

In the Open Theses & Dissertations community "Browse by Supervisor" needs to replace "Browse by Subject". We made the required changes on dev but it's providing this browse in the Open Research communities which shouldn't happen. We need to work out how to provide supervisor browse in Theses only. 

Could someone please shed light on this? We are running Dspace 7.4.

Regards,

Bryan

So, I found below configuration from the dspace.cfg file:

webui.browse.index.1 = dateissued:item:dateissued

webui.browse.index.2 = author:metadata:dc.contributor.*\,dc.creator:text

webui.browse.index.3 = title:item:title
webui.browse.index.4 = subject:metadata:dc.subject.*:text

Then, I have added:

webui.browse.index.5 = advisor:metadata:dc.contributor.advisor:text

and changed:
webui.browse.index.2 = author:metadata:dc.contributor.author\,dc.creator:text

This enables "By Supervisor" browse menu. However, when I go into the link, there is no item showing. I have run index-discovery but still no luck. Any suggestion please?

Running "bin/dspace index-discovery -b" command fixed it.
