Subject [jira] [Updated] (SOLR-13863) payload query function support for string encoded payloads (delimited_payloads_string)
Date Wed, 04 Dec 2019 12:00:00 GMT

Vincenzo D'Amore updated SOLR-13863:
------------------------------------
    Description: 
After a talk with Erick Erickson I was asked to incorporate this in Solr.

https://lucene.472066.n3.nabble.com/Solr-Payload-example-td4451173.html

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}}
