I have a server farm for three organisations (unfortunately they are all sharing the same user profile service app). There are three web apps with site collections (one web app with a site coll per org).
When we do a people search results from other organisations are displayed on the people search. Unfortunately we cannot use the organisation to filter the search results as everyone is a member of the same org in AD.
Is there a way to filter search results by the email address (i.e. from @ onwards)? if so how?
If not, is there an alternative way to achieve a people search that only returns people within a specific org based on their email address?
