Hello, I would like to ask you how to return data from the document tree. University =\> Faculty =\> Departments =\> Subjects =\> Annotation + syllabus. The document is stored in the ES "index": "university" =\> "fields": "Faculty" =\> "fields": "Departments" =\> "fields": "Subjects" =\> and syllabus and annotation. I search the annotation and syllabus, but I need to return the subject name (in híts). Can anyone help me. Thank you. Tom
