Hi, Alan,
I cc'd your question to the list, and please see my answer below:

No, it doesn't. "get.pathways.by.compounds(c("cpd:C00033",
"cpd:C00158"))" returns the pathways that
contain BOTH compounds. Try:
get.pathways.by.compounds(c("cpd:C00033", "cpd:C00033"))
[1] "path:map00010" "path:map00020" "path:map00430"
"path:map00440"
[5] "path:map00450" "path:map00534" "path:map00620"
"path:map00622"
[9] "path:map00660" "path:map00720" "path:map00920"
get.pathways.by.compounds(c("cpd:C00158", "cpd:C00158"))
[1] "path:map00020" "path:map00251" "path:map00252"
"path:map00630"
[5] "path:map00720"
Notice that you always have to give more than one compounds. If there
is only one compound, please
repeat it (sorry). This is because of a problem in the function. I
will try but probably can't fix
it quickly.

Try:
get.pathways.by.compounds(c("cpd:C00328", "cpd:C00328"))
get.pathways.by.compounds(c("cpd:C00033", "cpd:C00033"))
Actually get.pathways.by.compounds(c("cpd:C00033", "cpd:C00328"))
should return character(0). I
tried it via a java client.

Sorry for the inconvenience. Hope it works fine from now on...
