public boolean skipTo(int target) throws IOException
Spans
Returns true iff there is such a match.
Behaves as if written:
boolean skipTo(int target) { do { if (!next()) return false; } while (target > doc()); return true; }Most implementations are considerably more efficient than that.

public Collection getPayload() throws IOException
Spans
Spans.next()
is called for
the first time.
This method must not be called more than once after each call
of Spans.next()
. However, most payloads are loaded lazily,
so if the payload data for the current position is not needed,
this method may not be called at all for performance reasons. An ordered
SpanQuery does not lazy load, so if you have payloads in your index and
you do not want ordered SpanNearQuerys to collect payloads, you can
disable collection with a constructor option.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.
