New Filter operator-Time out.

Hi,

While trying to use new filter operator, it is resulting in time out.  The problem seems to be optimization of where condition which throws an syntax error when we try to activate the loop-enloop statement ( commented section). But does not produce any syntax error for the filter operator. Is there any specific reason for this behaviour. And how it can be corrected.

I am after the result which is produced when following loop-end loop is processed (no keys given)

Regards
