sum-function

Hello,

I like to use udmsearch with postgresql, but for searching I need a
funktion like the following. Every time I get an error. Is there
a possibility to make a work around?

udmsearch=> select sum( dict.word = 'mysql') from dict\g
ERROR:  Unable to select an aggregate function sum(bool)

What does the ERROR mean.

Thanks for any hint.

Christian

P.S. Sorry about the terrible English.
