Other than enumerating field names one can also add a seperator term between the repeating "fields" and use a search a single "field" by requiring that the separator does not occur in the match, roughly like: SpanNotQuery(SpanNearQuery(term1, term2), separatorterm) where each term is a SpanTermQuery in the Lucene field, not the same as the repeating "field" above.
