Filter be scripted field

Is it possible to filter by a scripted field? If so, how would the query look like?

I tried using the scripted field in a post_filter but it dies silently (0 matches)

The goal is to derive a new field as a predicate based on an existing field, and then filter on it based a condition...

GET /concession_test/_search
"_source": ["ref_nr","material_text_en"],
"source":"if(params._source.material_text_en.contains("TASK_1") || params._source.material_text_en.contains("QUEUE_1") || params._source.material_text_en.contains("TEST_1")){ return true } else { return false }"
"post_filter": {
"term": { "test_pred_1": true }

Thanks! :slight_smile:

script fields are only additional fields added to the top N results. They are not run for every document potentially matching the query. You would need to copy the script. However, I strongly discourage that in this case as you are using _source. Instead, use queries. For example, a bool query with should match clauses looking for TEST_1 or QUEUE_1 or TASK_1 should be equivalent?

Do you mean doing a script in a query context?

I had to use _source as the fielddata is off for our main server. Getting it changed is too much work :smiley:
