Parse error when using vector_chunks function

[PhilippSalvisberg]

The following statement is based on an example from https://docs.oracle.com/en/database/oracle/oracle-database/23/vecse/generate-and-use-embeddings-end-end-search.html:

SELECT d.id id,
       row_number() over (partition by d.id order by d.id) chunk_id,
       vc.chunk_offset chunk_offset,
       vc.chunk_length chunk_length, 
       vc.chunk_text chunk,
       vector_embedding(doc_model using vc.chunk_text as data) vector
  FROM documentation_tab d,
       vector_chunks(d.text by words max 100 overlap 10 split RECURSIVELY) vc;

it produces a parser error due to the vector_chunks function which uses non-standard parameters.
