Yahoo offers a second search form on what it calls the Search Options page (Figure 10.13). This form gives you three “advanced search” capabilities not available on the Yahoo home page:
You can limit your search of the Yahoo directory to categories or Web sites added within a specified time frame ranging from one day to four years.
You can change the number of matches that are displayed on each page of your search results following the initial summary page.
You can specify that you want to search Usenet newsgroup postings rather than the Yahoo directory.
