I’m building an Orchard module that uses Lucene search but it doesn’t look like it supports XOR (matches A or B but not both). Is this something I’ll have to roll myself or have I missed a setting somewhere that enables it?

Lucene does not natively support XOR operations. However you can simulate this behavior by writing your query as follows:
+(A B) -(+A +B)
