Could you please validate my use of highlighting to make sure I am using  
some unexpected behavior

I search on "\_all" (or another multi\_field created composite field) but  
then list my individual (primary) properties in highlight section. As  
long as I used the same analyzer on \_all and on those fields I am  
highlighting (stemming) I get correct highlights on my individual (primary)  
fields. If I understand correctly, as long as I do not tell ES to highlight  
on matched fields only, highlighting is pretty much independent from  
actual searching

Also I have a wildcard based highlighting question. The problem I am  
running into is ES exception when one of the fields matching wildcard is  
numeric (or date I guess).  
Is it possible to either have more flexible selection criteria (including  
say field type match) or have a lenient flag not to try highlighting text  
tokens in numeric fields (or highlight numeric tokens using lexicographical  
matching)?

Thank you,  
Alex
