hello guys,  is it possible to perform a search with a object as a query or its only possible with multisearch?  I would like to query in my fields like this

```search = client.collections['some-collection'].documents.search({
         'q': {"title": "something here", "rating":112},
        'query_by': 'brand',
     }
 )```

I would like to search like this to get an easier approach to a custom retriever in langchain.

`q` has to be a string.

So you would put any text fields in query_by and "something here" in the `q` parameter, and then rating:112 in `filter_by`
