More to the point, I have noticed some weird stuff with searches on the bay.

I'll get suggestions based on prior searches that clearly should have appeared in my original search, but did not. Framesets that are not newly listed that all fit my search criteria, but weren't included in the search results.

Also, in the past I have searched "Schwinn Super Sport" and gotten, say 75 listings. Then I punch in "Schwinn Supersport" and get 90, even listings that were not spelled as one word, but did not show up in the first search. No idea why it happens.
