Scopus had a scheduled outage last Saturday. I used it yesterday and got results I can't explain. I talked with their help desk (and later sent some screen shots), but I thought I'd alert folks -- I don't think it's just me (this time). (They haven't gotten back to me about this yet; I'll report when they do.) Their documentation says that searches aren't case-sensitive, but I got differing results with various versions of Factor VIII (factor viii, FACTOR VIII, etc.). I always put the phrase in quotes. While their documentation always shows Boolean operators in capital letters, there's no note (that I could find) that says they must be in capital letters. Yet when I combined several search statements using "OR", I got different results than when I combined the same search statements with "or". You Scopus searchers know that when you do a search there, and then go back to the search screen, your previous typing is still there, and you need to click "clear" for a blank search box. On their Advanced Search screen, I searched for two words using a proximity operator. I tried doing that same search several times, just by re-clicking "search" (NOT retyping anything) -- and got differing results. For one phrase I did it eight times and got five different numbers of hits. And yet, in both the Factor VIII and the proximity situations, when I used AND NOT to see the citations that were in a larger set but not in a smaller set, I got the "no results" message. I go absolutely nuts when I get inconsistent, non-reproducible results like this. I don't know if this is a wrinkle brought about by their work on Saturday, or whether it's been happening all along (shudder). Has anybody else noticed this?
