Subject Re: problems finding negative values
Date Thu, 05 Apr 2007 09:09:50 GMT
Ah! thanks.

Wrapping the term in quotes solves the issue, but i've tried escaping 
with \- as Yonik suggested and it doesn't. I guess there's no 
performance difference between both so I can live with quotes but 
anyway, for curiosity sake, should \ work?

thanks,
galo
