Hello Rohan

It looks you are saving the Key Value (that I assume is reminder of MOD) as ID. This is not a good practice as in future two students may result to the same mod like 2 mod 10, 22 mod 10 that time your data will show error while creating in database. 

So, you need to keep ID as auto number and save keyvalue in another attribute. 

Later on the condition will be filtered as -

keyvalue = NullIdentifier() or keyvalue = searchkeyvalue

As we do not have like operator for Integers

If still you want to keep the ID as KeyValue then use the below filter - 

HashTable1.Id = NullIdentifier() or HashTable1.Id = keyvalue
