Hey Binoi , can't understand why such complexity to be honest :/ Can you explain me why playing with :
edismax mm ( percentage of query terms you want to be in the results) pf ( the fields you want to be boosted if phrase matches ) ps ( slop to allow) Should not solve the problem instead of the 2 phases query ?
