Using a datefilter with caching
I''m trying to use a DateFilter to speed up some searches. The situation
is that a have an index with 200 000+ documents and I want to run a few
thousand alerts (basically stored searches) on only a small portion of
the index (documents added the last hour).
Is datefilter the best solution for the situation described above?...

status to *reasonably* comfortable with it.
Here's an issue I just cannot solve however as it appears to be some kind
of bug in R itself. But I won't claim that for sure.
I have a function as follows:
FindHighRow <- function(searchVector, highColumnIndex, thisDate, nextDate)
{
dateFilter <- GetDateRangeString(thisDate,nextDate)
filtered <- searchVector[dateFilter]
returnRow <- filtered[which.max(filtered[,highColumnIndex])]
returnRow
}
Running the lines BY HAND works fine. But as soon as I call it as a
function (passing in *exactly* the same values - and I have de...

perl bindings to Xapian::Query
...e to make a query myself, so I can
filter results by a specified value (in this case restricting by epoch
time after a certain value)
My code looks like this, and compiles, and appears like it should work
according to the perl source:
my $query = $qp->parse_query($querystr);
if ($datefilter) {
my $filterepoch = time() - ($datefilter * 60 * 60 * 24);
my $filterquery =
Xapian::Query->new(OP_VALUE_GE,I_DATE,$filterepoch);
$query = Xapian::Query->new(OP_FILTER,$query,$filterquery);
}
This appears to die on Xapian::Query->new with

Weighting recent results
I was thinking about this some more: Is there a reason I can't just
weight by some function of recency at indexing time?
$weight = get_weight_based_on_recency(...);
$tg->index_text($txt,$weight);
If I wanted to allow the user the option of searching either in
recency-weighted mode or not, I could index each document into 2
different databases, one with and one without.
This avoids

I think your issue here is that $filterepoch is a number rather than
a string (a Perl scalar can have different representations internally).
In t/valuerange.t this testcase works:
