The option when searching to have the results sorted by date of publishing
Instead of searching through the search box (upper right corner of each page):
Step 1. Click the "magnifier" icon (behind the search box itself)
Step 2. On "Forum Search" area, look for the following:
- "Message age:" - You can choose its range.
- "Search order:" - You can choose "Most recent topics first" and "Oldest topics first".
