How to compare 3 list field

[Cyber_X]

i have 2 index, index=index1 have file a, index=index2 have file b and c if i use search

(index=index1) OR (index=index2)
| stats values(a) as a, values(b) as b, values(c) as c

Search result will be:

         a                 b                c
      5336               
      5348
      5354
                          5324           5326
                          5337           5347

i want compare 3 list a, b, c and return values of a if a <=b and a>=c

In this search sentence it is not the result that is being presented.
Can I present inputs and results more concretely?
