NAME

Plucene::Search::DateFilter - Restrict searches to given time periods

SYNOPSIS

         my $filter = Plucene::Search::DateFilter->new({
                 field => "date",
                 from  => Time::Piece $from,
                 to    => Time::Piece $to
         })
         my $hits = $searcher->search($query, $filter);
 
 

DESCRIPTION

This class can restrict the results of a search to a set of dates. This requires a field to have been indexed using Plucene::Document::DateSerializer. See the documentation for that module for how to do this.

METHODS

new

         my $filter = Plucene::Search::DateFilter->new({
                 field => "date",
                 from  => Time::Piece $from,
                 to    => Time::Piece $to
         })
 
 

This creates a new filter. Either of "from" or "to" are optional.

bits

This is used by the searcher to iterate over the documents and return a bitfield specifying which documents are included in the range.
