I was browsing to see if there had been any Questions about taking precautions or defending against cougars. (There had been.) Questions about bears came up in the search -- that's reasonable. But this question about mayonnaise also came up. Mayonnaise? It didn't even talk about spoiled mayonnaise attracting cougars. How long does mayonnaise last unrefrigerated in the back-country? I don't expect a serious answer to this, or a fix. I think it is funny. Computers aren't ready to take over yet!
I'm not trying to say you didn't get the results you got, or that you're wasting anyone's time. I just don't know what search terms you used to get your mayonnaise result.
I tried cougars and got 22 mayonnaise free results.
I tried precautions and I got 91 results. I scanned the first 50 and didn't see mayonnaise.
I tried cougar precautions and I got 1 mayonnaise free result.
I don't work for StackExchange/StackOverflow so I couldn't fix the problem even if I could reproduce it. I think if you give us the query/search terms you used then we could answer why mayonnaise was in the result set.
