Thanks Steve, We have a smoking gun! I am on 6.5.1, and have tested in 7.1 and I don't see the same issue.
I can't upgrade just yet, however I have found setting mm=1 sorts this out in my case, giving me the following: (+(+DisjunctionMaxQuery((((web_name:metal (+web_name:rose +web_name:gold))~1))~1.0)))/no_coord I am still testing, however it looks positive so far. One thing I still noticed is the single word synonyms output "Synonym(...)" within the debug query, but multi-word do not - even in 7.1.0. Is this an issue? To be honest, I am not sure what it means, just something I noticed as a difference in the parsed query. Thanks again for your help, I thought I was going mad for a while.
