[Mulgara-general] Full-Text search

[Brian Sletten]

I use full-text search all the time. I am duplicating Nuno's results  
(as in none returned) but it works for my data. I'm wondering if  
aliasing is getting in the way but none of my attempts to remove it  
have worked either. I can't look at this any more at the moment but I  
will continue to investigate and get back to you, Nuno.
