Getting fields from query
Is there a way to get all the fields that are in a particular query?
Ultimately I'd like to restrict the fields that a user can use to search
so I want to make sure that there aren't any fields in the query that they
should not be allowed to search.

Thanks Jack, I ultimately want to limit but I'd take getting them if that
was available. I'll post to the lucene list though

Try asking the question on the Lucene user list - this is the Solr user
list.
Also, clarify whether you are trying to get the list of fields used in a
query or trying to limit the fields that can be used in a query. uf does the
latter, but your latest message suggested the former. You're confused us -
or at least me!
Look at how "uf" is implemented in Solr and then just replicate that in the
Lucene standard query parser. The solr standard query parser was originally
just a subclass of the Lucene standard query parser, but then they diverged
and Solr now has a copy of the Lucene query parser.

This actually may do what I want, I'll have to check. Right now we are
using Lucene directly and not Solr for this particular project, but if this
fits the bill we may be able to use just the query parser.

Hi Jamie,
May not be direct answer to your question but your Q reminded me edismax's uf parameter.
