Fess uses BM25.
See Similarity module in Elasticsearch documents.

Can we config the weight?

You can change app/WEB-INF/classes/fess_indices/fess.json and then run Reindex with Update Aliases.

I know this is old but I would like to change the weighting, at the moment, the current BM25 does not return great results, I have taken a look at the Similarity options and the one that appears closer to what I need is the “LM Jelinek Mercer” similarity option however I would like to switch to this option to test, can you tell me where I can change from default BM25 to “LM Jelinek Mercer”

Thank you for any help or resolution

It’s not changed. Please change app/WEB-INF/classes/fess_indices/fess.json and then run Reindex.
