Edit the query, go to the returned field tab panel, and add the "expression" field. The NaN score is a normal behavior when the result is sorted by a field (freq).

I also added more details related to the field setup in the initial instructions.

http://tinypic.com/r/156a4v6/5 and http://tinypic.com/r/2zipqmc/5 are the snapshots of my work you can see that i have add expression in return fields – Gopa Soft Apr 08 '12 at 19:11
Can you check if the "expression" field has the storage parameter set to "Yes" ? If not, check it, and execute the scheduler again. I added more details in the initial instruction. You may also check them. – Emmanuel Keller Apr 08 '12 at 19:13
May I request a snapshot of the scheduler job ? – Emmanuel Keller Apr 08 '12 at 19:21
Thank you! Can you read again the initial instructions, I added some informations related to the scheduler job and the required analyzer for the expression field. – Emmanuel Keller Apr 08 '12 at 19:28
