yup...certainly makes sense...

okay...i think i'm hitting something different now, and may have tracked
down what is the real problem; when i execute the above query from the
refdbc shell, i get the expected results, but when i do this from bash:

    refdbc -C getref ":KW:='52-67-5 \(Penicillamine\)'"

i get the "subselect failed" error, and the log shows the cut off
parentheses again...

7:pid=26684:Thu Jan 29 22:14:35 2004:SELECT DISTINCT t_xkeyword.xref_id FROM t_xkeyword, t_keyword WHERE t_xkeyword.xkeyword_type='REFERENCE' AND t_keyword.keyword_id=t_xkeyword.keyword_id AND t_keyword.keyword_name RLIKE '52-67-5 \\(Penicillamine\\'

if you want more logs, i'd be happy to oblige....

thanks again for all your work,
rc

btw: just added a primitive upload facility to the web front end....must
upload RIS data, but again, as a proof-of-concept, it seems to
work...feel free to upload stuff:
