boolean searches in Zeta perl?

[Andrew Leahy <aleahy@knox.edu>]

Hello,

I downloaded the Zeta Perl Z39.50 module at

	http://zeta.tlcpi.finsiel.it/z3950/zetaperl/

recently, and I've been using it to query a Z39.50 server.  But I have been
unable to figure out how to use the Zeta Perl Search method to perform
boolean searches.  Whatever I try, I end up with a parse error which, by
looking at the code, seems to originate in the zeta_yyinit call.  Does
anybody know if Zeta Perl can perform boolean searches?  If it is possible
to perform boolean searches with Zeta Perl, does anyone have an example of
how I should be formatting such a request?

Thanks for any information.
