Improved Sorting Options for Relevant Facets

TLDR Stefan proposes a feature for sorting facets based on other fields not just hit counts. Kishore Nallan agrees and emphasizes the need for the facet value to remain constant across different documents.

What options do we currently have to show more relevant facets? I know that there is an open issue for that to sort facets, but is there anything I could do right now?

What do you mean by more relevant facets? Facets are sorted by count of hits.

Stefan

Yes, but I have a use case, where the count of hits is not that relevant, for example:

Imagine thousands of products where each product has 20 ingredients or so.

Almost all of them contain water, but that is pretty irrelevant.

I would like to show the ingredients in the default view that "make the difference" in a product.

Right now the only way I see on how to get those results is by creating a separate field in the schema that only contains the "relevant" ingredients.

Interesting. It almost feels like we need to introduce a way to sort the facets on some other field. But the thing is, the association between an ingredient to a specific recipe may not be captured simply by some popularity score. If that is possible, then having a sorting condition on faceting will help.

Not sure if I get the last part correctly but sorting a facet based on another field is something that I also described in this issue: https://github.com/typesense/typesense/issues/521

So this feature would def. fix my issue.

*ingredients should be an array in this comment (fixed)

Would the calories value remain constant for all instances of that specific ingredient across different documents? If so, then this should be possible without any major rework.

Stefan

For my use case this would be the case

I think if that value wouldn't be static across ingredients then it wouldn't make much sense, because then two facets would mean two different things

Kishore Nallan

Correct, yes I think facet has to be constant.
