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?
