Lance Norskog commented on SOLR-1485:
-------------------------------------

Julien Noche posted last August that he had to create a new query parser variant of dismax.
I cannot find an example of a query string in his post.

[Using Payloads with DisMaxQParser in SOLR|http://digitalpebble.blogspot.com/2010/08/using-payloads-with-dismaxqparser-in.html]

Use cases for a payload-based query:
* a raw byte stream
* a serialized Java String
* a number
* a boolean value in the payload
* "is there a payload?"
* boosting a document if the search term has a payload
** the payload is a number (packed float) created by 

Most of these can be encoded into a payload. But there are no matching decoders.
There is no code that pulls the payload and uses the data.

payloads.
