Hello there.

I'm having a terms facet returning different things than I expected.

My docs have this structure:

{  
{a: { name: "a"}},  
{b: { name: "b"}},  
{c: { name: "c"}},  
{d: { name: "d"}},  
}

, where those a...d vary according to the doc.

When I do a terms facet on "field":"name", appears to me that ES is only  
getting the first term on the doc, cause I get 3 terms while I was  
expecting 166.

Any tips / comments on this? Whenever I have this kind of very dynamic  
mapping I have troubles doing this kind of queries...

Cheers

-pedro

are you faceting on a none analyzed field?

"The field used for facet calculations must be of type numeric, date/  
time or analyzed as a single token."

E.g. if you like multiple values for one field you can use an array of  
strings
