I can query historic task instances by candidateGroups

Hi Ingo,

{
	"orQueries": [
	    {
	        "taskHadCandidateGroup": "a1"
	        
	    },
	    {
	        "taskHadCandidateGroup": "b1"
	    },
	    {
	        "taskHadCandidateGroup": "c1"
	    }
	    ]
}

I thinl that ‘or’ is the above format, but the printed SQL statements are connected with ‘and’.

What I just described is not clear enough. You can refer to this question.
