Example:

blah [{  
type : group,  
name : wombat  
accounts : [a b c]  
},  
{  
type : group,  
name : ferret  
accounts : [x y z]  
}]

Originally our queries were returning the incorrect answers if we did: name  
: ferret & accounts : [a b] we would get data back. We realized that we  
had to create a mapping for nested document and set the fields as  
"not\_analyzed". That works great except when character case is not  
conformant. Name could be "Ferret" or "feRret" etc. How do I map this puppy  
to be not\_analyzed and ignore case? Plenty of discussions about it then  
being analyzed. But nested does not allow for that.

Thanks

You can configure a custom analyzer, with keyword tokenizer and lowercase  
filter. keyword tokenizer will make sure all the text is a single token,  
and lowercase will lowercase the characters.

Tried that and the funky results started showing up again. Where "ferret" &  
"a" would return a doc. Obviously doing something wrong.
