Can we have some date-related advanced super ninja search options? Something along the lines of:

```none
maxage:30               find posts less than 30 days old
from:yyyy-mm-dd         find posts no older than yyyy-mm-dd
to:yyyy-mm-dd           find posts no newer than yyyy-mm-dd
```

or, more explicitly (as [suggested by Jon Seigel][1]):

```none
postedbefore:<timestamp>
postedafter:<timestamp>
modifiedbefore:<timestamp>
modifiedafter:<timestamp>
```

The other day I was trying to find a question to refer to but I couldn't find it in the sea of "relevant" search results. Maybe date ranges would speed up some queries too?
