Hi Jonty, I think you have three possible solutions:
1. Use the collapse component with your name field for not have any duplicates documents. 2. Create a simple logic in your index with flags, like one flag to determine the first element of the same document (in your example you will have three differents documents and the fist one wiill have this flag=true). If the search only have name, you will have to set this flag to true, if not, the dept or the student will be defined and you will have one document returned. 3. Do a post-processing of your data. Maybe you will have more solutions but these are what i have thought right now. Regards, Marco Martínez Bautista http://www.paradigmatecnologico.com Avenida de Europa, 26.
