Reading the docs I see for the Ranking Parameter:

query_by_weights

that its default value is:

If no explicit weights are provided, fields earlier in the query_by list will be considered to have greater weight.

Is it possible to know what exactly are the values? I am trying to tweak the weights, and it would be great to know what the actual defaults are. For 3 params, would it be 3,2,1?

For 3 params the default weights would be 4, 2, 1. For 4 params it would be 8, 4, 2, 1 and so on

And for 2 params?

That's right

OK thanks!

What issue are you seeing with those weights?

The search does not work at all

You should see any errors returned in the API response

OK, got it.

"Number of weights in `query_by_weights` does not match number of `query_by` fields."

In fact my original question was wrong. What I would like to do is change the weighting of the SORTBY fields... Is that possible?

Could you elaborate on that what you mean by "weighting" as it relates to sorting? Because when you sort by multiple fields, we use a tie-breaking mechanism. So if you have field1,field2,field3 as sorts, we sort by field 1, and then if two documents have the same value for field1, we use the value for field2 to break the tie and so on.

Basically, what I would like to do is boost a bit the results (put them closer to the top) given the second sort element. Knowing that are second sort element is not a queryBy field (since it is the number of sales of that product!).

Ah, for that you want to use this mechanism: https://typesense.org/docs/guide/ranking-and-relevance.html#ranking-based-on-relevance-and-popularity

OK, understood. Now can you confirm that having one bucket only basically would mean that the text match (first sort element) would become useless?

OK, excellent!
