[Qexo-general] join pattern match

[shn]

Hi all,

 

New to xml and qexo so forgive me if this seems trivial. I'm using kawa-1.6.99.jar

 

I am joining names and ran across some strange behavior with initials. It seems like the '.' is a wilcard but even as such isn't predictable? The data, xql and results follow. Any feedback would be appreciated.

 

Is there another operator that would perform a strict match, or a way to escape any wildcards? Where should I be looking for info on wildcards, operators, ...

 

Thanks,

Kevin
