I agree with the sentiment you expressed. You can find some examples by 
googling for "Solr payloads", but although there is a schema field type for 
indexing specialized terms with payloads, there is no other support unless 
you add custom code, such as a custom Similarity and a custom QParserPlugin. 
In other words, it's really only halfway there (or less) to being "ready for 
prime time." It's basically an "expert" feature for the DIY crowd.

There are probably plenty of applications for payloads, but Solr doesn't 
come close to offering a functionally complete "toolkit" for exploiting them 
out of the box (without custom code.) For example, I don't think there are 
any function query value sources for payloads - although you could always 
roll your own with custom code.

Subject: What does SOLR actually do with Payloads?


I am trying to figure out payloads and , as far as I can tell, Solr does
not actually do anything with them.

Wiki says that they can be generated, but nothing seems to use them for
anything. This mailing list had 4 or 5 questions on payloads in last six
months and nobody answered those.

So, is there there some sort of end-to-end path/example of using them or
are they there just because Lucene has them and people have to write custom
code to use them?
