> I have the per-store pricing problem but payload function handles only numbers.
> Stores can also be in different countries, for example would be useful having with the
price also the currency and other attributes related to the store.
> We could have add support for string encoded payloads fixing function query named *payload*.
> Example document:
> {
>  {{  "id":"my sample doc",}}
>  {{  "currencyPayload":[}}
>  {{    "store1|EUR",}}
>  {{    "store1|USD",}}
>  {{    "store3|GBP"}}
>  {{  ]}}
>  }
> Querying Solr with
> {{fl=payload(currencyPayload,store3)}}
> would generate a response like the following:
> {
>  {{  "response": {}}
>  {{      "docs":[}}{
>  {{         "id":"my sample doc", }}
>  {{         "payload(currencyPayload,store3)":"GBP"}}
>  {{      }]}}
>     }
>  {{}}}
> And executing `payload(payloadCurrency,store2)` returns `EUR`, and so on.
> You can use `payload` even as sorting function.
> {{sort=payload(payloadField,value) asc}}
