Let me revise my question. After reading through the source code for Lucene a bit more, I realize that using updateDocValues isn't really an option. This leaves me with querying all the data, modifying each document, and replacing the original. Not as efficient as I was hoping for, but sufficient. This does work for me, but with one major flaw. Facets are lost because they aren't loaded into the Document when I search. Is there any way to retrieve the existing facet fields into the document before I write it back out?

I see IndexWriter.updateDocValues appears to be the closest solution, but it takes a Term and I'd prefer to use a Query. Is there any way to accomplish this in Lucene without querying and updating each entry manually?
