I have a general distrust of all search-related services.
For example, I was trying to stalk an old girlfriend on Facebook so I typed her name into the "Search" box at the top of the page. The instant prediction results were showing 5 profiles with that exact name, and at the bottom it had the link to "See more results", under which it said "Displaying top 8 results" (8 != 5). To make matters worse, when I clicked the "more results" link, the resulting page said "No results found for your query".
But I noticed the filter was set to "All results", so I clicked the "People" filter and boom, there's 25+ profiles with the name I searched for.
So why does it initially show 5 and tell me there's 8? Why doesn't the "All results" setting also show "People"? And why can't I find my ex girlfriend? I just want to know she's doing badly without me.
