Abnormal result when using search function on people view in NAB

Hello,

Our company address book is indexed. (NAB)

We use Employee ID Field to identify each person in the company.

When we do a search for a NON existing Employe ID by a search on the standard view “_people” ;

  • sometimes : we have an empty view result with message "0 documents in view “_people matched your search”

==> good message and good display

  • sometimes (for another value) we have all document in the view displayed with message "0 documents in view "_people matched your search

==> good message but bad result

do you know why ?

thanks in advance for your help

Kind regards

Nicolas
