I would ask if you need nested documents at all. If you can denormlize the docs it's often much easier. In your case I can think of several options: 1> just index a separate field for each subject. Solr handles a couple of hundred fields with ease. student id : 123 student name : john maths: 90 English :95
student id : 123 student name : john marks: math_90 english_95 You have one "marks" field and each token has it's associated score. Probably want to left-pad if you want to do range queries here, i.e. math_009, math_098, math_100. That way you can express [math_009 TO math_020] and have it "do the right thing". Use payloads for the scores.
