Custom FunctionQuery in Solr

[Ali Husain <al...@outlook.com>]

I'm trying to implement something like this in Solr 6.6

Custom Solr FunctionQueries. Solr FunctionQueries allow you to modify the ranking of a search query in Solr by applying functions to the results.

The goal is to take a field called 'foo' from all the documents and modify that field with a custom function.


Has anyone been able to do this successfully? I can't find any helpful documentation. All the stuff I've found is broken and doesn't work.


Thank you,

Ali

bq: The goal is to take a field called 'foo' from all the documents

I don't really understand that. You use the contents of the field to
modify the score of a doc with a custom function query.

If you want to modify the field that's returned with a document, you
use a DocTransformer.

If you want to modify the contents of a field during indexing,
consider a ScriptUpdateProcessor.

_How_ does it fail? What does your code look like? How is it broken?
Details matter.
