How do i set the security for this option.

As you can see above i have a list of jobs posted.

And this view is the summary view as you might already know and i have an saperate action apply beside the job details tab which is for applying the candidate for the particular job.

But when i click apply, the candidates that i have applied for other jobs also are visible.
I want to know how can i use the queryfilter option so that when i come to the summary view of a particular job and click on apply i can only see the candidates that have applied for that particular job.
Ex: I have a job posting called coforge with an job posting id of "00004" and when i go on its summary view i can see the whole job details and when i click on the apply tab , i should only see the candidates that have applied for the coforge job only. Is that possible using the queryfilter function. Please guide me through it.
