www.nytimes.com/2011..."The four-page report, drafted by Portugal, said the Council members held three broad views on the issue, without GOING INTO DETAILS."
www.nytimes.com/2011..."Mr. Vaknin refused to GO INTO DETAIL about possible rules of engagement or to describe under what conditions settler response teams might open fire. "
It seems that either both "go into detail" and "go into details" are valid, or that one is wrong.
Now if I want to intensify "go into detail(s)", then I have two options:
"go into much detail"
"go into many details"
What should I do?
