For various reasons, we'd like to eliminate the sort step.
Our current query interface takes a start time and end time as an input range:
RangeFilter rf = new RangeFilter("day", start, end, true, true);
hits = searcher.search(query,rf,new Sort(new SortField[]{
new SortField("timestamp",SortField.STRING,true)}));
The idea is to stuff the start and end into the query object. During scoring,
documents closer in timestamp to the start should score higher (exact match to
the start time should score the highest).
Where would I start ?
-- Extend (subclass ) BooleanQuery ?
-- Extend BooleanScorer2 ?
-- Extend DefaultSimilarity ?
How do I get a score the timestamp field in the same range (normalized) as the
term score? What precision can I get given that the timestamps are in
milliseconds since 1970 ? That is, Jan 23, 12:00:00:000 should score higher
than Jan 23, 12:00:00:001
Thanks
