# Plucene::Search::DateFilter - phpMan

## 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.
