Problem Description
The "size" parameter controls the number of documents returned by a _search against a semantic_text field. However the maximum value appears to be capped at 19.
For certain use-cases, like RAG to an LLM, nineteen docs may be rather limiting to send to an LLM for augmentation, most particularly if the documents in the index are short.
Steps to Reproduce
Index documents with a field mapped as semantic_text data type. Search (with "match" or "semantic") that field with size 20 or larger.
