Reusing the sample code from my previous demo, I build a table with 130 sentences describing AI Tools and then use SQL to run the sort of queries that you'd expect RAG to use against an "internal knowledge source".
Here's a preview of the sentences loaded :
SQL> select count(*) from my_data_source;
COUNT(*)
----------
130
SQL> select my_sentence from my_data_source fetch first 5 rows only;

The embeddings are then computed and loaded into the target table using the same query (the HuggingFace model ALL_MINILM_L12_V2_AUGMENTED has already been loaded with the ONNX RunTime engine with the same code as in the previous blog post) :
insert into my_data_vectors
select ds.id as id, my_sentence, to_vector(et.embed_vector) sentence_vector
from
my_data_source ds,
dbms_vector_chain.utl_to_embeddings(
dbms_vector_chain.utl_to_chunks(dbms_vector_chain.utl_to_text(ds.my_sentence), json('{"normalize":"all"}')),
json('{"provider":"database", "model":"ALL_MINILM_L12_V2_AUGMENTED"}')) t,
JSON_TABLE(t.column_value, '$[*]' COLUMNS (embed_id NUMBER PATH '$.embed_id', embed_data VARCHAR2(4000) PATH '$.embed_data', embed_vector CLOB PATH '$.embed_vector')) et

I now test a few "Retrieval" queries thus : (Note how the queries return different results with smaller VECTORE_DISTANCE as I refine them)

In the second pair, I change my query from "image" to "How can I use AI to edit Images ?" I get an improved set of responses (again with a smaller VECTOR_DISTANCE).
In the last pair, when I change my query from "coding" to "Tell me of a Coding Assistant", I get responses with a better match to my query.
As noted in my previous blog post, the "LLM" is actually a "MinLM" called "all-MiniLM-L12-v2" from HuggingFace.
