Hi, I have an index that has a tracking by ID. For each step that id pass writes a DOC to elastic. But I'm trying to make a filter that does the following validation. It passed Step2 but did not pass at Step4. Exemple: ID: 123 STEP: A ID: 123 STEP: B ID:123 STEP:D Filter: STEP:B AND NOT EXIST DOC WITH STEP:C Return: ID: 123 ---

It could be possible with [bucket selector aggregation](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-pipeline-bucket-selector-aggregation.html) over ID and STEP terms aggregation. Note the [max\_buckets limitation](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket.html). ---
