When applying one filter you can use the shorthand syntax as you have above.

When applying multiple filters, you need to use the full filter syntax documented here: [https://swiftype.com/documentation/app-search/api/search/filters#combining-filters](https://swiftype.com/documentation/app-search/api/search/filters#combining-filters)

```auto
"filters": {
  "all": [
    { "brand": ["brand1"] },
    { "price": ["price1"] }
  ]
]}

```
