> New query function to read and sort string payload field
> (delimited_payloads_string)
> 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 a new function query named *spayload* that helps to read and
> sort payload field *delimited_payloads_string*.
> Example document:
> {
> {{ "id":"my sample doc",}}
> {{ "currencyPayload":[}}
> {{ "store1|EUR",}}
> {{ "store1|USD",}}
> {{ "store3|GBP"}}
> {{ ]}}
> }
> Querying Solr with
> {{fl=spayload(currencyPayload,store3)}}
> would generate a response like the following:
> {
> {{ "response": {}}
> {{ "docs":[}}{
> {{ "id":"my sample doc", }}
> {{ "spayload(currencyPayload,store3)":"GBP"}}
> {{ }]}}
> }
> {{}}}
> And executing `spayload(payloadCurrency,store2)` returns `EUR`, and so on.
> You can use `spayload` even as sorting function.
> {{sort=spayload(payloadField,value) asc}}
