You can sort your search results by either date posted or by relevance. To sort, first run a search by clicking the blue arrow on the Jobs tab - you cannot filter the automatically-loaded recommendations - then make a selection from the Date Posted section in the left hand column.
When you have selected the time period the bubble will be highlighted blue and your results list will update.
