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 sufficien
I'm trying to write an efficient update to match with a Query and update all
matches with specific fields (while maintaining the other previously set fields
on each document). I see IndexWriter.updateDocValues appears to be the closest
solution, but it takes a Term and I'd prefer to use a Query.
