Ok, Jayant, thanks.
I can only give you some tips that you might want to try out.
Sometimes the problem you describe was caused by not boosting the
field. This does not apply to your case as you are calling
super("rating", 5f);
I am comparing your code to my code (that is working fine) to see
where the differences are. The only thing I see is that I am extending
RawFieldQueryFilter and not FieldQueryFilter. At the same time my
plugin.xml has fields="field_name" and not fields="DEFAULT".
I do not know the theory behind the difference between a
RawFieldQueryFilter and FieldQueryFilter, but you might want to try
changing those two items.
Let us know the result.
