Below is a document struct form one of our collection,

}

How we can use filter_by query to search "ratings->source" and "ratings->rating" ? I used below but looks its not enough

{
  "searches": [
    {
      "q": "*",
      "query_by": "",
      "filter_by": "ratings.{rating:=G && source:=mpaa}",
      "sort_by": "",
      "exclude_fields": ""
    }
  ]
}

Returning below response,

{
  "results": [
    {
      "code": 400,
      "error": "Could not find a filter field named `ratings.{rating` in the schema."
    }
  ]
}

Which version of Typesense are you on?

its docker image tag 26.0.

Yup, this syntax was introduced in v29.0

Ok. Thanks

Could you provide a reproducible example like this one? https://gist.github.com/jasonbosco/7c3432713216c378472f13e72246f46b/

Ok Shall try to prepare one and Share. But I do have another Q. Is that feature limited only to search, but multi_search ? Because I am using

http://{{TYPESENSE_SERVER}}:{{TYPESENSE_PORT}}/multi_search?collection=titles_20250804

Body :

{
  "searches": [
    {
      "q": "*",
      "query_by": "",
      "filter_by": "ratings.{source:=mpaa}",
      "sort_by": "",
      "exclude_fields": "description_embedding,tags_embedding"
    }
  ]
}
