Hi there,

I need to search in multiple fields where I do not know field names in  
advance, so I can't use multi\_match syntax. So I found, that \_all field  
aggregates all fields set to be included in all in mapping. Unfortunately  
it returns different result set, that multi\_match. Here is complete test  
set for Sense.

What I'm doing wrong?

thank you for any response.
