Problem Description

#138989 adds auto-prefiltering for MATCH queries on semantic_text fields that are using dense vectors.

However, filters that are not translatable to Lucene queries will not be pushed down, and thus will not apply prior to the knn query.

For KNN queries, this is solved by falling back to an EXACT NN. That would be one way to address this for MATCH too.

Steps to Reproduce

Example query:

FROM test_index
  | WHERE MAX(some_field, 10) == 10
  | WHERE MATCH(dense_semantic_field, "some query")
