org.apache.lucene.search.payloads.PayloadSpanUtil
Experimental class to get set of payloads for most standard Lucene queries. Operates like Highlighter - IndexReader should only contain doc of interest, best to use MemoryIndex.
WARNING: The status of the Payloads feature is experimental. The APIs introduced here might change in the future and will not be supported anymore in such a case.
