How do I preform a facet search for all documents against a type like this?

{
  "facet": true,
  "index": true,
  "infix": false,
  "locale": "",
  "name": "categories.lvl0",
  "optional": false,
  "sort": false,
  "type": "string[]"
}

You should be able to facet by just sending "facet_by": "categories.lvl0" as a search param. What problem are you facing?

Kishore Nallan That's for responding 🙂 I want all the documents where lvl0 is Furniture { "categories.lvl0": ["Furniture"] } for example, or all the documents where lvl1 is Sofas, like { "categories.lvl0": ["Furniture"], "categories.lvl1": ["Sofas", "Poufs"] }

That's filtering and you can do that via filter_by , e.g. filter_by=categories.lvl0:= Furniture

Ok, thanks! Side-question: Do you recommend the whole { "categories.lvl0": ["Furniture"], "categories.lvl1": ["Furniture > Sofas", "Furniture > Poufs"] } dance where you add the parent and a seperator into the lvls? I know Algolia recommends that

I think our examples also follow the same pattern, tagging Jason who can maybe suggest if there's a better way here.

Another related question 🤔 Kishore Nallan Jason I'm now using this query q=*&filter_by=categories.lvl1:= Furniture > Shelving and storage&per_page=32 for a category page, and it works great. But how does the curation work here? From what I can tell curation is only for the query (* in this case) and not for the filter? If i want to move item id 123 to the top of the Furniture > Shelving and storage page and document id 456 to the top of the Furniture > Tables and side tables page, how do I do that?

Curation based on filter_by rules is available on recent RC builds. See: https://github.com/typesense/typesense/issues/536#issuecomment-1238746446

Since it is on a RC build, it's not available through the Typesense Cloud UI then?

We can upgrade from our end, you can schedule an upgrade from the UI.
