Search functions return wrong content in `ailab-db`

[k-allagbe]

Description

Search functions now return funny values for the content field.

def search(cursor, query_embedding):
    """Search matching documents with a given query and return a dict."""
    data = {
        'text': ' '.join(sys.argv[1:]),
        'query_embedding': query_embedding,
        'match_threshold': 0.5,
        'match_count': 10,
        'weights': json.dumps(FINESSE_JSON_PARSED_WEIGHTS)
    }

    cursor.execute("""
        SELECT *
        FROM search(%(text)s, %(query_embedding)s::vector, %(match_threshold)s,
                   %(match_count)s, %(weights)s::JSONB)
    """, data)
    # turn into list of dict now to preserve dictionaries
    results = cursor.fetchall()
    from pprint import pprint
    pprint(results)
    return [dict(r) for r in results[0]["search"]]

Printed value for "who's the president?"

1. The chunk's full text or snippet is expected to be received in the content field.
2. The subtitle values also look funny, although I'm not sure what is supposed to be received there.
3. I suggest we receive the value (list of results) of the search field instead of [ { "search": [...] } ]

For comparison we receive this from azure-db:
