Topic (sorta) says it.  Example:

[08:49:21 ids:~/broarchive/03-28-2013$] zcat dns.log.gz | grep light | 
bro-cut -d

[08:49:25 ids:~/broarchive/03-28-2013$] zcat dns.log.gz | bro-cut -d | 
grep light

x.x.x.x    53      udp     43494   www.lighting.com      1       
C_INTERNET      1       A       0       NOERROR F       F       T

I'd like to grep out the content before sending to bro-cut as it takes 
a fraction of the time (as shown above).  I've made sure that no 
colorization is happening.  Any hints on how I can get this to fly?  
Thank you.
