Is the query-side term weighting intentional?

[RonanKMcGovern]

For example running a query like:

WITH query_vector AS (
    SELECT bm25_query_to_svector(
        'documents_content_bm25',
        'Paris capital france',
        'pgvector'
    )::sparsevec AS qv
)
SELECT qv FROM query_vector;

yields:

                     qv                      
---------------------------------------------
 {4:0.26759678,8:0.4648064,13:0.26759678}/17

This suggests there is some weighting of the three tokens in that query.

My understanding is that bm25 typically has no term weighting, but perhaps I'm misunderstanding the implementation (or what is considered standard for bm25).
