Mikhail Khludnev commented on SOLR-13863:
-----------------------------------------
This name clashes with the first order payload (a datum per term position in a
doc). It should be done via N separate DV fields. Overall it doesn't look
generic enough to get into common codebase.
> payload query function support for string encoded payloads

> 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}}
