 Description   

Translate:

s[i] == 'c'

to:

{ $eq : [{ $subStrCP : [<s>, <i>, 1] }, "c"] }

Similarly for other comparison operators (not equal etc...).

The comparand must be a char constant (it will be converted to a one-character string during translation because the server doesn't have the char data type).
