Does array search support push down?

I’m trying to query an array in ElasticSearch

data: "names":[{"name":"allen"},{"name":"bill"},{"name":"dave"},{"name":"poter"}]
goal: "select names from table where array_contains(names.name, "bill")"
but spark won’t do predicate pushdown if SQL statement use array_contains function. hint: names.name = ["allen","bill","dave","poter"] I’ve tried

select * from table where array_contains(names.name,"bill") -- and select explode(names.name) as name from table as t1;select * from t1 where name = "bill" -- and select * from table where cast(names.name as string) like '%bill%' All failed to do pushdown, any other ways to do it?

with this change in Spark 3 it might be possible to push down array_contains now? https://github.com/apache/spark/pull/28366

possibly just add this elasticseach datasource to spark.sql.optimizer.nestedPredicatePushdown.supportedFileSources ?
