Negation in EQL not working

Question

Total records are about 12000, property P_COLOR defined for 4000 of them.
The query
collection()/record[P_COLOR="red"]
returns expected result, i.e. all records, where property equals "red".
However, when I try to fetch records by property existence, it returns 0.
For example
collection()/record[P_COLOR]
OR
collection()/record[not (P_COLOR)]
return ZERO.
I found in official docs that such syntax is supported by Endeca:
Using negation on properties
EQL supports filtering by the absence of assignments on records. By using the not operator, you can
filter down to the set of records which do not have a specific property assignment.
For example:
collection()/record[author_id]
returns all records with the "author_id" property, while:
collection()/record[not (author_id)]
returns all records without the "author_id" property.
Guys, what's the catch?
Would be very grateful for your replies.

Hi,
I am trying to run this sql & it dosen't comes up with the right results:
select * from (
select distinct cost_center from GL_GL
where length (cost_center)=8
where cost_center NOT in (select cost_center from MAP_FLAG)
It is not liking the NOT IN command highlighted in black. Not sure what is wrong, please advise.
Tx& how do you expect to know exactly what constitutes "the right results"?
