Is there an existing issue for this?

  • I have searched the existing issues

What would you like to be added?

add some optimization to multi-and or multi-or exprs.
for expr like ' A < 5 && B == 'a' || json['a'] = 'c' ....' which has long multi sub exprs. now milvus execute them one by one as user specified.
but some heavy operations like json and array ..etc , them cost a lot. if we can postpone them and let light expr execute first. using preceding expr info to help reduce scan data.

Why is this needed?
