Sure that's an ugly, but I'd just use:

SELECT to_tsvector(REPLACE('mike/john', '/', ' '));

and the same with to_tsquery();

[GENERAL] tsearch2 parser configuration

Is it possible to configure the tsearch2 parser?  I'd like a very dumb
parser that splits on everything that is not [a-zA-Z0-9.].  The
default parser seems to work well on my dataset except for the '/'
character ... it doesn't split mike/john into two lexemes.  And ideas?

Thanks!
