# Ferret::Search::RangeFilter

## Summary

RangeFilter filters a set of documents which contain a lexicographical range of terms (ie "aaa", "aab", "aac", etc). See also RangeQuery

## Example

Find all documents created before 5th of September 2002.

    filter = RangeFilter.new(:created_on, :< => "20020905")

## Number fields

See RangeQuery for notes on how to use the RangeFilter on a field containing numbers.

### Public Class Methods

new(field, options = {}) → range_query click to toggle source

Create a new RangeFilter on field `field`. There are two ways to build a range filter. With the old-style options; `:lower`, `:upper`, `:include_lower` and `:include_upper` or the new style options; +:<+, +:<=+, +:>+ and +:>=+. The options' names should speak for themselves. In the old-style options, limits are inclusive by default.

## Examples

    f = RangeFilter.new(:date, :lower => "200501", :include_lower => false)
    # is equivalent to
    f = RangeFilter.new(:date, :< => "200501")
    # is equivalent to
    f = RangeFilter.new(:date, :lower_exclusive => "200501")

    f = RangeFilter.new(:date, :lower => "200501", :upper => 200502)
    # is equivalent to
    f = RangeFilter.new(:date, :>= => "200501", :<= => 200502)

    static VALUE
    frb_rf_init(VALUE self, VALUE rfield, VALUE roptions)
    {
        Filter *f;
        char *lterm = NULL;
        char *uterm = NULL;
        bool include_lower = false;
        bool include_upper = false;

        get_range_params(roptions, &lterm, &uterm, &include_lower, &include_upper);
        f = rfilt_new(frb_field(rfield), lterm, uterm,
                      include_lower, include_upper);
        Frt_Wrap_Struct(self, NULL, &frb_f_free, f);
        object_add(f, self);
        return self;
    }
