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.
