Scenario for the following user
DisplayName - CULTRARA, Robert
UserId - cultrarar
Email -

When I search for a user using the People Picker tool, here are the outputs based on my search queries:

  1. If I type "cultra", I get both displayname and userid in two separate entries for each claim, however I don't get the email claim which contains cultra in the email address claim.

  2. If I type "robert", I don't get any results for this user, though Robert is part of the DisplayName claim

  3. If I type "r.cultrara", I get only " in the search results.

However what I expected is when I type "cultra" in the search query I should have got either one user with all this claims or I should have got all three claims. The results we get doesn't match that theory.


The search is done by design, we are searching for the matching first chars in the field and SharePoint claims provider appends star (*) at the end of search string.

so for a search : cultra you get :

DisplayName - CULTRARA, Robert
UserId - cultrarar

so for a search : r.cul you get :
Email -
