How to include the multi Picklist field in Fetch Record Criteria in Deluge Script?

Hi All, Need an help. I have a problem to restrict the fetch record based on multi pick list value( Look up field having capable to select more than one value- bigintlist).

Problem Outline. I have a Attendance Form which has a Absent-Students multi picklist and date field. for getting the student information for a month or certain period.

To get the Attendance details for a particular student i have to restrict it based on course and semester details. but not on student id to the absent-students lookup field.

Currently i am doing it as follows

Loop though each attendance record ,
for each attendance record get list of absent students.
Loop though each student and see which record matches the required students id

This is not efficient as i am looping unnecessarily.

Here is a sample code

for each attendanceRecord in Fill_Attendance[Semester == semesterId && Subject_field == subj && Academic_Batch_Field == BatchId]
        {
            for each student in attendanceRecord.Absent_Students
            {
               // If student is absent for 1 class in a month then unnecessary iteration gives the limitation error of delige script
                if(student == studentId)
                {
                    totalClassesAbsentTillDate = totalClassesAbsentTillDate + 1;
                }
            }
        }

Error received :

Number of statement execution limit exceed Line:(32)

Any idea of to construct the fetch record including bigintlist as one criteria?

Thank You
