Hi,  
We save our data in a range of time-series indices like logstash-YYYY.MM.DD.

As the data expands too large, we have to limit the search range instead of just `logstash*`.

For example, how to search last 7 days? I need something like

```auto
/<logstash-{now/d-7d} to {now/d}>

```

Or , is regexp supported?

Create an alias that includes the last 7 days indices.
