You can change the Search Template (templates/default/
search.tpl)
Lines 83-90 (in T7.00) you'll see something similar to this:
{$lang.NEWER} <input type="text" name="newerval" size="2" class="form-input" value="3" />
<select name="newertype" class="form-select">
<option value=""></option>
<option value="d">{$lang.DAY}</option>
<option value="w">{$lang.WEEK}</option>
<option value="m">{$lang.MONTH}</option>
<option value="y" selected="selected">{$lang.YEAR}</option>
</select>Replace what you have with what's above.
In the first line, you'll want
value="3" (like above) if you want to search NEWER than
3 DAYS/WEEKS/MONTHS/YEARS.
In the last line you see
selected="selected" in the
YEARS row, because you want YEARS selected rather than WEEKS (you want to
cut/paste that, not copy/paste -- you don't want "selected" in there for years & weeks, just years)
