Last week, I emailed this to the support staff at Google Scholar; I'm still waiting for a response:
----- I am deeply in love with Google Scholar, but I think I may have found a bug. The use of the "or" operand actually seems to reduce the number of hits relative to the use of individual terms. Two examples: neurotransmitter: 224,000 hits neurotransmitters: 144,000 hits neurotransmitter OR neurotransmitters: 177,000 hits serotonin: 488,000 hits dopamine: 663,000 hits serotonin OR dopamine: 508,000 hits When I do a regular Google search, the "or" operand seems to behave more as I'd expect it to: neurotransmitter: 5,770,000 hits neurotransmitters: 4,020,000 hits neurotransmitter OR neurotransmitters: 6,120,000 hits serotonin: 8,880,000 hits dopamine: 9,040,000 hits serotonin OR dopamine: 15,800,000 hits If at all possible, can I hear back from you on this one?
