ES|QL: score function pushdown error #133462
Description
Description
A simple query like the following will result in an error:
FROM books
| EVAL s = score(match(title, "Tolkien"))
error:
[2025-08-22T17:48:16,126][ERROR][o.e.b.ElasticsearchUncaughtExceptionHandler] [runTask-0] fatal error in thread [elasticsearch[runTask-0][search_coordination][T#1]], exiting java.lang.AssertionError: LuceneQueryEvaluator requires shard information
at org.elasticsearch.compute.lucene.LuceneQueryEvaluator.<init>(LuceneQueryEvaluator.java:57)
at org.elasticsearch.compute.lucene.LuceneQueryScoreEvaluator.<init>(LuceneQueryScoreEvaluator.java:35)
at org.elasticsearch.compute.lucene.LuceneQueryScoreEvaluator$Factory.get(LuceneQueryScoreEvaluator.java:71)
This most likely has to do with how Evals are pushed down, such that we then try to execute score without the shard information.
extract_snippet will most likely have the same error - so we should find a generic solution that can be applied to any function that requires shard info in order to be evaluated.
