Ok, bros. I think there is no option method to filter aggregation significant terms bucket list result using different field.
Based on elasticsearch documentation Significant Terms Aggregation Parameters, which refers to Terms Aggregation Filtering Value. There is no other option than filter using partition expression and filter values with exact values (which i have been using as above, "exclude" param).
So i create other way around by getting the comic ids which i want to exclude and store it as excludeComics variable in array. Then use the excludeComics var in exclude param. And boom, there you go. Filtered significant terms aggregation bucket list result.
