SpanFirstQuery modification to aid term boosting based on position.
-------------------------------------------------------------------
Key: LUCENE-1093
URL: https://issues.apache.org/jira/browse/LUCENE-1093
Project: Lucene - Java
Issue Type: Improvement
Components: Query/Scoring
Reporter: Peter Keegan
This is a request for a modification to SpanFirstQuery that would allow term
boosting based on a term's distance from the beginning of the document.
This modification to SpanFirstQuery would be that the Spans returned by
SpanFirstQuery.getSpans() must always return 0 from its start() method. Then
the slop passed to sloppyFreq(slop) would be the distance from the beginning of
the indexed field to the end of the Spans of the SpanQuery passed to
SpanFirstQuery.
