: If you just need to transform an individual result, that can be done by a : custom DocTransformer. But from your email, I think you need a custom : SearchComponent.
if your PostFilter has already collected all of the info you need, and you now just wnat to return a subset of that information that corrispponds to the individual documents being returmed on the current "page" of results (ie: the current DocList) then a custom DocTransformer should probably be enough as long as your PostFilter puts the computed data in the request context. see for example how the ElevatedMarkerFactory works in conjunction with the QueryElevationComponent... https://cwiki.apache.org/confluence/display/solr/Transforming+Result+Documents https://cwiki.apache.org/confluence/display/solr/The+Query+Elevation+Component -Hoss http://www.lucidworks.com/
