Erik Hatcher updated SOLR-1280:
-------------------------------
Attachment: FieldsUsedUpdateProcessorFactory.java
This is just a quick implementation to demonstrate a field being added
dynamically which lists all the fields on a given document. Making this
configurable to specify the field name and perhaps list fields (by pattern,
possibly) to include or exclude.

> When dealing with highly heterogeneous documents with different fields per
> document, it can be very useful to know what fields are present on the result
> documents from a search. For example, this could be used to determine which
> fields make the best facets for a given query.
