Hi,
We're seeing slow response time when we apply datefilter. A search that
takes 7 msec with no datefilter takes 368 msec when I filter on the last
fifteen days, and 632 msec on the last 30 days.
Initially we saved doing
document.add(Field.Keyword("dtstamp", dtstamp));
and then change to doing
document.add(Field.Keyword("dtstamp", DateField.dateToString(dtstamp)));
where dtstamp is a java.util.Date
Either way the results are slow.
We search doing the following:
days_ago_value = Long.parseLong(days); //could throw NumberFormatException
days_ago_value = new java.util.Date().getTime() - (days_ago_value * 86400000L);
hits = indexSearcher.search(query, DateFilter.After("dtstamp",
days_ago_value));
Not only is the query slow, but it seems to be slower the more results
it returns.
Any suggestions?
TIA,
Dror
