Thanks @evanlitttle but this is not that clear for me about the steps to go through. Should I create a data type “Dispute” with all the related inputs as a Dispute’s field?
Just to give you an example:

Dispute is the data type (Dispute ref, Dispute name and Dispute surname are Dispute 's fields)
Occurence 1
Dispute ref=TEST
Dispute Name= Smith
Dispute Surname=John

Occurence2
Dispute ref=TEST2
Dispute Name= Dupont
Dispute Surname=Pierre

in a given page, as soon as I type in TEST2, I would like that all related fields are displayed, meaning Dupont and Pierre

Hope it clarifies my need
