I was looking through some lucene source codes and found the following class org.apache.lucene.search.payloads.PayloadSpanUtil
There is a function named queryToSpanQuery in this class. Is this the preferred way to convert a PhraseQuery to PayloadNearQuery? Also, are there any performance considerations while using a PayloadNearQuery instead of a PhraseQuery?
