# intersect [fe_intersect]
::::{note}
This setting is only available in the [period](/reference/filtertype_age.md) filtertype. This setting is strictly optional.
::::
```yaml
- filtertype: period
source: field_stats
direction: older
intersect: true
unit: weeks
range_from: -1
range_to: -1
field: '@timestamp'
stats_result: min_value
```
The value of this setting must be `True` or `False`.
`field_stats` uses an aggregation query to calculate either the `min_value` and the `max_value` of the [`field`](/reference/fe_field.md) as the [`stats_result`](/reference/fe_stats_result.md). If `intersect` is `True`, then only indices where the `min_value` *and* the `max_value` are within the `range_from` and `range_to` (relative to `unit`) will match. This means that either `min_value` or `max_value` can be used for [`stats_result`](/reference/fe_stats_result.md) when `intersect` is `True` with identical results.
This setting is only used when [source](/reference/fe_source.md) is `field_stats`.
The default value for this setting is `False`.
